Total Pro Sports - Shaq has really taken to this whole Twitter thing.  So much so that now he is challenging other professional sports athletes to competitions in their own sports.  First on the List?  Lance Armstrong.

Shaq tweeted Armstrong saying, "I challenge u to a race any time any place, it's time someone challenged u."  So what kind of response did he receive from Lance?  How about, "Alright Shaq, you're on.  To quote the great Ricky Bobby, 'Bring it on trying to bring me down.'"  In case you need some clarification, I think Lance means to say he accepts.  So now that the invitation has been sent, received and accepted, the only question is when will the big race happen?  Hopefully soon, once Shaq gets a bike and biking shorts custom made.

It is interesting to note that Shaw also tweeted Danica Patrick, challenging her to a race on wheels.  I don't think they will be making that custom Indy car anytime soon though.
