Hell I would fight either (as long as I have the best doctors by my side), ofcourse I would throw myself down if I had to in the first 3 seconds lol (but the money is worth it lol).
Incidently I met Tyson in NY once (mutual friend), & he seemed ok there, though very much on his own. Don't think he has many friends (which is alright for the non-mentally challenged lol), but he is always tense & looking for a fight. When someone has no control of their anger like that, they can never control their re-actions. Thus the biting or whatever would be necessary.
I would watch to see what dirty tactics he would throw (keep having a vision of lewis going down & tyson kicking & jumping on him). Tsyon wants to kill Lewis, not out-box him (remember that).
