Mike Tyson's proving age ain't nothin' but a number ... 'cause the boxing legend popped the hood at weigh-ins Thursday morning, and Iron Mike's living up to his moniker!
He's ripped and rarin' to go.
58-year-old Tyson and 27-year-old Paul both stepped on the scale Thursday morning in Dallas -- about 36 hours before they'll try and take each other's heads off in the ring -- a fight Mike told us would be the "biggest in the history of life."
If fans weren't quite sure whether Mike was taking the fight seriously, safe to say we have our answer.
