Liar Liar. The morning after his son makes the "cannot lie for a day" wish, Fletcher (Jim Carrey) wakes up in bed after a fling with his female boss.
Boss: Mmm, that was incredible! Was it good for you?
Fletcher: (turning head and smiling sincerely) "I've had better!"
The next 5 minutes are probably the funniest I've ever seen in a movie. When I saw it at the cinema the entire audience was roaring.
