I met Mike Tyson in a gift shop in Las Vegas once. On the outside, he was tough as nails back then, but was very personable and pleasant even signing an autograph for me when asked. We talked a bit about boxing and I appreciated his taking time.
The clerk said he was shopping for a little diamond trinket for his girlfriend. Hard on the out side, but a softy on the inside, I think. He is a person who when the red curtain comes down, you better not be on the receiving end.
