Plunged

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.
