Got a spare plunger lying around? Why not take a dump in it, plunge it onto your best buddies car windshield. Smashed doodoo butter lying in wait under a seemingly lame prank of a plunger on the windshield.
a) Plungers are hard to get off glass. Especially on a hot day. This means you have to apply force to get the plunger off the windshield.
b) Once enough force is applied, well, shit flies everywhere.
c) There is still a mess even after the punchline is over and you're still using a squeegee to smear around some deep brown.
d) Windshields aren't the only thing plungers filled with shit fit on.
Note: Make it loose.
