There is actually a sign in many high school copy rooms specifically telling students not to photocopy their butts. The hilarious part is that the reason they give is because it wastes toner.
For the ultimate office prank, make enough copies that you can tape them end to end (so to speak) in a chain that you can then feed into a scroll-fed fax machine, closing the loop as it feeds: enter the fax number for someone you don't like, and you've just sent them an infinite series of butts. Or at least, wasted all their toner. You'll need about half-a-dozen copies to pull this off successfully without complications.
