Revenge On Junk Mailers
The best way to ensure you get no more junk mail from a specific company, try this prank. Usually junk mailers will send an enclosed envelope along with the rest of the mail to get you to reply. Maybe to signup for something. On the enclosed envelope, you will also see something that says "No Postage Necessary if mailed in the U.S." this means they pay the rate of the return. So if you send it back stuffed with numerous junk mail letters they have to pay the rate, reguardless of how heavy you make it.

V-Chip Prank
All televisions sold in the U.S. since 2000 that are larger than 13 inches have a V-Chip installed in them. The average TV watcher doesn't know this, so they don't even know what its for. Well, the V-Chip was designed to keep children from watching unsuitable programs. So anybody that has access to the tv remote control can set the v-chip up. Just go over to your victim's house, fiddle around with the remote and set the v-chip to only be able to watch children's programs. It will frustrate your victim when he is ready to watch The Sopranos or CSI only to find out all that is available is Sesame Street and Dora The Explorer

Show him that it makes it appear to look broken underneath water. Then have him put both his thumbs on the tabletop so you can place the glass of water on top. Then walk away and leave him alone to figure out how to get it off.
