Mooshroom Diet for Cows

Alright, listen up, dummy. You 'member when I said that you ain't got much upstairs? I meant it. This is a pun, see? "Mooshroom" sounds like "mushroom," and cows eat grass and stuff, so you're leadin' someone to think of normal mushroom. But get this: cows *also* moo, so it's a play on words 'cause it sounds like they should eat "moo-shrooms." Get it now, bonehead?
