A bowling phenom in the Special Olympics has just challenged Prez Barack Obama to a White House roll-off ... and he'll probably kick Barack's butt.
Kolan McConiughey, a Special Olympics competitor who has bowled three perfect 300 games, tells TMZ that the Prez has to score a lot higher than 129 to beat him. Kolan says he bowls an average of 266.
Kolan -- who works at a grocery store in Ann Arbor, Mich. -- said he'd love to go to the White House to beat Barack on his own lane. Kolan said, "He's cool, but he can't beat me."
We posed the challenge to the White House. They said "no comment."
