Funniest thing in a movie ever

I was just watching 16 Candles a minute ago. It's an awesome 80's movie, and if you've never heard of it you can go look it up.

Are you done? Good.

There's one scene where the main character is talking to her grandparents at her house, and it becomes very awkward:

Grandmother: Oh Fred...she's gotten her boobies.
Fred: (Chuckles) I'd better get my magnifying glass...
Grandmother: And they are so perky! (reaches out hands)

Then we see Sam, the main character, in her room.

Sam: I can't believe I just got felt up by my grandmother...

I was laughing so hard I almost pissed my pants. So what's the funniest thing you've ever seen in a movie?

 

The inbetweeners fish punch scene series 2 episode 1 :p

 

That girl in the movie is also in Breakfast club.
I watched that in Drama not that long ago.

 

I like that part in Breakfast Club when the weird emo girl reaches over in the background and grabs that knife out of the chair xD. At first I didn't see it then everyone was laughing and rewinded it and I died. Heheheheheheh
