When I was a kid, playing a prank on someone usually involved toilet paper, soap or shaving cream.  Although all three were relatively harmless, now as an adult I can appreciate the true nuisance they are.  Thankfully, I have yet to wake up one morning to find my trees decorated with swaths of toilet paper myself.  But, if I was going to be on the receiving end of a prank, a flock of plastic pink flamingo lawn ornaments in my yard would have to be my prank of choice.  Clearly, there are others who have thought so as well.
