The Wedding Party Scene
I really liked the movie but the funniest part was the wedding scene. Bob Newhart being freaked out by Kevin Kline touching him were classic.
The No-Troll Zone
Bob Newhart is hilarious throughout the whole film. I love the little shot of him at the wedding where he does like a 2 second dance before becoming manly again. I think possibly the best exchange Bob and Kevin have in this whole movie is the scene where the Principal calls Howard to his office. It has some killer lines including
Principal "Are you a homo-homo-homo..."
Howards "Home room teacher?"
Principal "Homosexual."
And when he asks Howard if he can walk for him so he can see if he's gay. So funny. Dear Buddha, please send me a pony and a plastic rocket.
