I'd have to say Dumb and Dumber. After what.. 12 years its been out? i still crack up watching Lloyd pull up to the Austrian girl at the beginning of the film.. "Mmmmm... Austrian!?"
Other ones that came to mind were
Scary Movie 3
Ace Ventura 1, 2
Laurel & Hardy ("Here's another nice mess you've got me into!") LOL
Aladdin (yea Disney... so what) was fuckin jokes as well
Dude... no place in town has Billy Madison on DVD... wtf!?
