Here's the worst:
What is Whitney Houston's favorite kind of coordination?
HAND EEEEEEEYYYYYYYEEEEEEEEEEEEEEEEEE
I'm sorry.
Here's one of my favorites (it's something along the lines of this):
So a guy asks a girl to prom, and goes to rent a limo. The line is super long, and he waits two hours, but eventually he gets it. Then he goes to get himself a suit. The line at the cashier is, again, very long, and he waits for an hour, but eventually he gets his suit. Then he goes to get a haircut, and waits in line for two hours. Then he goes to get her flowers. The line is, again, very long, and he waits for an hour and a half, but eventually he gets the flowers. Finally, he's at prom with her. They dance, then she says she is thirsty. He goes to get her something to drink, and there is no punchline.
Hehe.
I'm sorry.
