My friend and I are in a prank war right now. It all started when I hid a dead skunk in his spare tire compartment in his car. He smokes a lot of weed and thought that was the causeof the smell. He eventually found it. He tried to get me back by peeing on my car (I know, lame right?) and now it is my turn. I already have a piece of my own poop saved to write "BIG C WAS HERE!" on his window, but I also want to fill his windshield wiper fluid thing with urine. Do you think this would work? Also, comment any other ideas you might have.
