"Na, na, na, na, na, I know fractal geometry."

Just when Mommy and Daddy started to make you feel so smart about taking your first doody in the potty, three-year-old William Potter comes along with his 140 IQ to make you feel like a total turd.

Willy’s score makes him one of the brightest young chaps in the world and qualified him for Mensa, the club for brainy people.

This little dude’s so intelligent he makes even the gifted and talented students seem as dense as Sarah Palin. While you and all the other marker-sniffers fumble through your ABCs, this kid’s well on his way to becoming fluent in Spanish and Chinese and wooing older chicks who dig the nerd-type.

Mum, Lynn Goldstraw, says of the little Einstein, “He’s like a sponge. You only have to tell him something once and he remembers it.”

Well, Willy Potter, you better remember this: look both ways and don’t talk to guys in white vans with cute puppies. Because if there’s one thing that savants like you tend to get a big fat “F” on the report card of life for, it’s street smarts.
