Adam Sandler hated playing a foul-mouthed stand-up comic in upcoming movie Funny People - because he felt dirty telling rude jokes now he is a dad.

The Wedding Singer star began his career at comedy clubs while he was studying at New York University, before he was spotted by a talent scout and hired as a writer on hit show Saturday Night Live.Sandler abandoned stand-up as his movie career took off, but returned to his roots with a role in Judd Apatow's new film.But the actor felt guilty performing raunchy jokes while his two daughters were asleep at his family home.He says, This was stuff I hadn't done in a long time. I haven't talked that filthy in front of people. I went on stage and was as filthy as I could be. Then I would drive home and I'd be in my driveway alone and think of my two little kids sleeping and I'd just feel like the biggest, dirtiest human being.
