At first, I thought the cell phone prank was just mediocre.. But the more I see it, the funnier it gets. Next time I'm on the bus on the way to school and someone calls me, I'm gonna answer my phone like that "HELLO!!!!" heh
The music they play in the background makes it even funnier...
The hedge maze prank has to be my favorite, though - although the camo-netting in front of the meter maid comes in at a close second.
