Bad grandpa!
Okay well there are two movies that made me laugh so hard I threw up!! The first was The Nutty Professor. It was that scene when Eddie is dressed up like various family members and they are all passing gas at the dinner table.
The second is Rat Race. It was the scene when Whoppi Goldberg and her friend were in that land speed rocket. When they stop and get out of the rocket. Oh man, I'm giggling just thinking about it. :)
Since we've recently been talking about it.....
Monty Python and the Holy Grail
"And the Lord spake, saying, "First shalt thou take out the Holy Pin. Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in My sight, shall snuff it."
Its outdated but Airplane followed by Young Frankenstein.
