Once upon a time there was a mule. His name was Homer. He lived
in a very lush pasture, so had many opportunities to pig out on
fluffy green grass.
One sunny day, as Homer was grazing, his peaceful afternoon was
interrupted by a loud, obnoxious noise. It was a big, fat biker
dude on a Harley. He parked his bike right in Homer's favorite
corner. This upset Homer immensely, so he waited for old fatty
to leave the scene, then he moseyed over to the Harley. Taking
a quick look around, Homer backed up to the bike and took a huge
dump. When he was done, he hurried off over to the other side of
the pasture.
Well, the biker dude returned to find his prized possession all
covered in steamy shit. Glancing around, he spotted a cow in the
field. He pulled out a gun, shot the cow, then took the body to
the butcher to be portioned into meat.
Homer stood under a tree, chuckling. He didn't like that old
cow anyway.
