#1 Mike Tyson vs Justin Beiber
Everybody knows what would happen in this fight - Mike Tyson would knock the Biebs' head clean off his shoulders. The problem is what comes next - his death would send his record sales skyrocketing and at least for a month after it, his songs will be the only thing you hear, everywhere you go.
But look at the bigger picture - we will never have to face the pain of a new Justin Bieber song or watch his stupid mug on TV. So I'm sure we can put up with a temporary inconvenience for long term bliss.

And it's still not too late to hope and pray for this to happen - Mike Tyson's still alive and punching and unfortunately, so is Justin Bieber. If anyone can put a stop to that, it's Iron Mike. Fingers crossed, fight fans, fingers crossed.
