You mean Forrest Gump? It had a few moments that were funny, but more tongue in cheek kinda funny. Like when he is sitting at the bus stop talking to two people and this older man laughs at him because he thinks Forrest is lying about being a millionaire, then after the man leaves, Forrest shows the woman sitting there the picture of him and Captain Dan on the cover of Fortune or some similar magazine (can't really remember what the magazine was) and she has a shocked look on her face. Or when Forrest is running across a football field during a team practice trying to get away from some bullies and coach Bryant sees him and enrolls him in college to play ball for Alabama. Or when he got shot in the buttocks in Vietnam and went to the White House and told the president he'd been shot in the butt and the president whispers that he would like to see that, so Forrest pulls down his pants and shows his bum. So no, not slapstick funny but there were still humorous scenes.
You can't tell I have seen that movie 20+ times, can you?
