Oh my gosh! I have alot of these.
Im surprised a couple of you really like "Please put your hands up before exiting- buh bye!"

Gets me every time!
Ok- this one is kind of creepy, but on the Tower of Terror when that little girl is singing "Its raining, its pouring" Like the whole time, I kind of like that.
On Soarin, when that guy has those Mickey Ears on "Store all extra items in the bag below you, even those little beauties" I think that's hilarious, just his expression.
Muppets 3D- Idk his name, but the rat guy who comes on in a Mickey Mouse costume and he goes "What!? They dont know the difference, they're tourists!" or something similiar to that.
Dinosuar- "The road might be a little bumpy (goes to scene with a little girl about to fly out of the car)... what's the worst that can happen??" and then during the ride "You're not going to make it, you're not going to make it, you made it!!!!" Kinda weird.
Ellen's Energy of course! There are some funny parts in hers, I love it.
Ok, I also like The Laugh Floor's little video before the show "Remember, ventriliquists are not funny" and alot of other things like that.
Last... I would have to say i also love "move to the DEAD venter of the room" I love the CMs in there, the last one stared me down the last time. He won though, and when I looked back at him he had disappeared. Freaky
Long list, sorry!
