A List of the 20 Funniest Movies – Help!

I have a terrific friend who is coming home from the hospital tomorrow to recuperate from heart surgery. Her doctors say that this kind of surgery triggers feelings of sadness and depression. So I want to put together a list of the 20 funniest movies to send her family. I am trying to come up with a truly inspiring list. However, I need your collective genius.

If you got two minutes, would you post the funniest movies you have ever seen?

Here is my first brainstorm:

The Full Monty
Waking Ned Devine
Auntie Mame
Love Actually
Trading Places
Gentlemen Prefer Blondes
Calender Girls
Saving Grace
How to Marry a Millionare
Bringing Up Baby
The Philadelphia Story
The Seven Year Itch
My Favorite Wife
