The Big Aristotle, Shaquille O’Neal has been a voracious user of Twitter, becoming in the process one of the most popular people on the useless service. Always one up for some competition, Shaq sent this message to Lance Armstrong, “I challenge u to a race any time any place, it’s time someone challenged u.”
Lance replied back “Alright Shaq, you’re on. To quote the great Ricky Bobby, ‘Bring it on trying to bring me down.'”
I only see Shaq winning if he gets to ride his dope motorcycle.
Ever one to seize an opportunity, Shaq also challenged Danica Patrick to a race, somehow though methinks he wouldn’t fit so much in an F1 car…
