Stupid descriptions

He's a few clowns short of a circus

She's a few fries short of a Happy Meal

He's an experiment in artificial stupidity

He's a few beers short of a six pack

She's dumber than a box of hair

He's a few peas short of a casserole

She doesn't have all her Cornflakes in one box

The wheels spinning but the hamster's dead

He's one Fruit Loop shy of a full bowl

She's one taco short of a combination plate

He's a few feathers short of a whole duck

He's all foam...no beer

The cheese slid off her cracker

Body by Fisher, brains by Mattel

He has an IQ of 2, but it takes 3 to grunt

She couldn't pour water out of a boot with instructions on the heel

He fell out of the Stupid Tree and hit every branch on the way down

His intellect is rivaled only by garden tools

He's as smart as bait

He doesn't know much but leads the league in nostril hair

Her elevator doesn't go all the way to the top floor

He forgot to pay his brain bill

Her sewing machine's out of thread

His antenna doesn't pick up all the channels

His belt doesn't go through all the loops

If she had another brain, it would be lonely

He's missing a few buttons on his remote control

There's no grain in his silo

He's proof that evolution can go in reverse

His receiver is off the hook

She's several nuts short of a full pouch

Her skylight leaks a little

Too much yardage between the goal posts

Not the sharpest knife in the draw
