Charlie Sheen gave career advice to children at an elementary school.
The 'Anger Management' star decided to pay a visit to his daughters Sam, 10, and eight-year-old Lola's school as part of career day, and while the talk was "funny" the kids reportedly had "no clue" who he was.
A source told RadarOnline.com: "It was funny and Charlie answered questions from the kids about being a television star. The talk lasted about 10 minutes and then he was gone. The other parents certainly know who he is, but the kids had no clue that Charlie was a major Hollywood actor. Now they know."
It's thought the troubled actor - who is now engaged to porn star Brett Rossi - displayed amicable behaviour towards his ex-wife Denise Richards, although they didn't speak to one another.
The source added: "[The couple did not] exchange any words, as she sat on the opposite side of the room."
Meanwhile, the pair are to become involved in a bitter court battle in the coming weeks, as Charlie is reportedly planning an appearance in a Los Angeles court in a bid to decrease the $55,000 a month he pays to Denise for child support of Sam and Lola.
And the 48-year-old actor is looking to evict his ex-wife from the luxury home he owns and has allowed her to live in with her three children.
An insider added: "Charlie hasn't spent any time with the girls in several months and thinks it's ridiculous that he continue to pay Denise $55,000 every month."

A friend told Hollywoodlife.com: "Kristen asked Rob what his thoughts were about her adopting another dog for her birthday. Kind of like a gift for her and Bailey, because Bailey wants a friend. She's been like, 'If you see a rescue dog in Toronto and you think the dog would be a good match, adopt him and bring him back to LA'."
Animal lover Kristen, who will celebrate her birthday on April 9, is still in contact with her 'Twilight' co-star Rob, 27, who ended their four-year relationship last year after he struggled to get over her brief fling with married director Rupert Sanders in July 2012, and she wants him to be involved in her birthday celebrations next month.
The source added: "Kristen wants to celebrate her upcoming birthday with her close friends in LA, and she wants Rob to join them.

Speaking on 'Live with Kelly and Michael', he said: "I've been working on that for the last year and we just completed it. It's really incredible. I did train like a boxer, I'm actually rather good with my hands now.
"That's one of the great things about working on a boxing film, you definitely get the physique together, but greater than that was to act opposite Edgar Ramirez, Robert DeNiro, I mean, it was just incredible."
Though he has an impressive body from making the movie, Usher admits to having a "weakness" for junk food.
Asked which of the coaches on 'The Voice' eats the most junk food, he admitted it was himself and added: "My favourite junk food is Australian liquorice, I have a weakness."

While there is no prospect of a romance between the pair, the duo did discover a mutual love of 1991 film 'The Man in the Moon', which starred Reese Witherspoon, and Lena claims shaped her ideals about relationships.

The 17 year old was invited to meet the royals after he and his sister helped rescue stranded flood victims in their canoe.
Joseph told the Kent and Sussex Courier newspaper: "I just asked Prince Charles for a selfie and he let me. I have added it to my David Cameron one which I got when he was down here.

"You heard the first portion of the album on songs like 'The Other Side' and 'Marry Me', but then it switches to the other side with 'Talk Dirty'."
He added: "It represents everything I've got, everything I was feeling in the moment."
Jason is yet to announce whether his new album will be released in the UK.

George Michael was "too afraid" to ask Amy Winehouse to duet with him.
The 'Careless Whisper" hitmaker was keen to duet with the 'Back To Black' singer, who died of alcohol poisoning in 2011, and even wrote a song for her after she died, but claims he was too nervous to discuss a collaboration when she was still alive.
He told BBC Radio 2: "I was always too afraid to ask to duet with her. I love the fact that she finally duetted with Tony Bennett just before she died. It must have been amazing for her father."
Amy recorded the song 'Body And Soul' with celebrated jazz singer Tony in 2011 before she died and her father Mitch has always been a big fan.
George, 50, who rose to fame in the duo Wham! with Andrew Ridgeley, also wrote a song for Amy, 27, before she passed away but never had the chance to show her it.
He added: "And also, there's no question in my mind, one of the things that was so special about Amy was her parents' taste in music and she had the great advantage of having fantastic music on in the house as a young child, and I think that really makes a difference. Most of us don't have parents with fantastic record collections."
He said his own father, Jack Panos, never let him buy records when he was younger and he was left to listen to what was lying around the house.
George said: "And that was like a Henry Mancini album, a couple of Greek albums. But basically there wasn't a lot of stimulation going on in the house musically."

James Lock has been pictured allegedly cheating on Danielle Armstrong with former 'Big Brother' contestant Sallie Axl.
The tattooed model has come forward as the woman at the centre of a cheating scandal on 'The Only Way is Essex' and shared a snap on Twitter of her groping Lockie's genitals in what looks to be a nightclub.
While Lockie has continuously denied cheating on Danielle - who was informed he had played away while in Brighton in 'TOWIE' recently - the lothario appears to have been caught out and has been engaging in a war of words with Sallie on Twitter.
Sallie began the altercation by tweeting: "Is this for real ?? James lock told me he was splitting up with his misses anyways in this series. #jokes #towie (sic)"
Danielle - who had previously likened herself to a 'lobster', and claimed Lockie had traded her in for a 'fish finger' - fired back at Sallie.
She wrote: "I'm actually in fitss that this silly s**g would claim to be the 'fishfinger' from Brighton #NoRespectForHerself #FameHungry #OverIt (sic)"
Things took a dramatic turn when model-and-DJ Sallie posted a photo of the pair looking intimate, cheekily captioning it: "I'm defo lying (sic)"
James has since responded to Sallie's allegations and pleaded that his on/off girlfriend "doesn't deserve this".
He wrote: "Enoughs enough!! @Sallieaxl listen if I really wanted to f*** u I would have paid u £500!
"The only person who's the victim on all this is @Daniarmstrong88 she doesn't deserve this and I've been a complete p****!!!! (sic)"

'Line of Duty' will return for a third series.
Executive producer Simon Heath has claimed the production team behind the hit police corruption drama have already begun plotting ideas for another series, but the show isn't expected to return until creator Jed Mercurio completes work on his new Sky 1 medical drama 'Critical'.
Simon told Broadcast: "We've already started talking about potential fertile story areas for series three.
"[We've discussed] what that might be and what the character or characters might be. But there's plenty of mileage in police corruption.
"Once [Jed] is finished on 'Critical', he'll be ready to go."
The critically acclaimed drama - which stars Keeley Hawes as Detective Inspector Lindsay Denton - will end its dramatic second series tonight (19.03.14) and the BBC have taken extreme measures to ensure spoilers don't leak out before it airs.

Not even BBC's director general Tony Hall has been given access to the series finale.
He said: "I am completely hooked on 'Line of Duty' at the moment. I have actually asked if I can have recordings of the end of the series, but like everybody else I have to wait."

David Beckham has undertaken a two-week camping trip through the Amazon forest for a new documentary.
The former soccer star made a secret visit to Brazil with friends Dave Gardner and Derek White and filmmaker Anthony Mandler to make a 90-minute programme, which will air on BBC One in June to tie in with the World Cup.
Charlotte Moore, BBC One controller, said: "In this special documentary for BBC One, David Beckham embarks on a top-secret expedition to the Amazon that will see him encounter the other side of Brazil and journey through the tropical rainforest, a TV first for the global icon."
David - who has four children with wife Victoria - camped, cooked and fished during the expedition, and channel bosses promise the resulting programme, which was made to showcase the natural beauty of the South American territory, will be "unforgettable".
Helen Jackson, managing director for content at BBC Worldwide, said: "This is an unforgettable documentary set in the heart of the dense Amazon rainforest following David Beckham.
"Through his eyes, audiences will experience life in the jungle, something so distant from David's life on and off the pitch and in the glare of the world's media."
The documentary doesn't yet have a name.

"They kindly asked us to do a homage to 50 years of BBC Two. It's turned out to be less of a homage and more of a homicide. Whoops."
BBC Two's acting controller Adam Barker added: "'From 'The Likely Lads', the very first comedy the channel showed in 1964, to more recent highlights including 'Miranda', 'Rev', 'The Trip', 'Twenty Twelve' and 'The Wrong Mans', BBC Two has a long and proud history of growing and supporting new comedy talent and I'm delighted to be announcing a range of brilliantly funny new content that celebrates 50 wonderful years of wit on the channel."
The cast of 'Goodness Gracious Me', including Meera Syal, Sanjeev Bhaskar, Nina Wadia and Kulvinder Ghir, are also reuniting for a brand new 30-minute special which will feature iconic characters from the 1990s series as well as new ones.
