ESPN Mike Tyson is no match for 'Mike Tyson' in 'Mike Tyson's Punch-Out!!'

Mike Tyson may have been a fearsome competitor in his boxing career, but anyone who owned a Nintendo Entertainment System back in the day knew that there was only one version of Iron Mike that was nearly unbeatable: the one that appeared in ''Mike Tyson's Punch-Out!!'' On Tuesday night's episode of ''The Tonight Show Starring Jimmy Fallon,'' Tyson took on his virtual self and learned the same lesson the rest of us did when we were kids: If you don't dodge his uppercut, Mike Tyson will knock you out in one punch.

I never managed to beat Mike Tyson in ''Punch-Out!!'' and neither did anyone on my block. Some kid at school claimed that he did, but he never could replicate the feat when pressed. At least he didn't lie about beating that one ''Battletoads'' level. I'm still not convinced it can be beaten.
