I would have beat him within an inch of his life the first time he buttered that floor no matter the "get even", and he would have butter in every possible orifice, copious amounts. He would have pissed his pants everytime someone even mentioned butter... why, he would have to wear depends to buy popcorn at the movie house... in his nightmares, the boogyman would look like a one pound tub of Land O Lakes sweet cream unsalted... a VERY big one that guy was a sissy anyway.. after three times it was "next time I see you"
I would have buttered his pillow just so he smelled it while he slept also. idiots deserve the same trick played on them.
