A dumb plan that someone thinks is genius but is actually just messy and stupid.
He said he’d get rich by selling his old socks. Now he’s got a sock business and still smells like his childhood.
She tried to cheat on her math test by writing answers on her fingernails. Now she’s got smudged math and a teacher who’s mad.
He tried to lose weight by only eating pizza and drinking soda. Now he’s bigger and still eats pizza.
