Iron Mike, indeed.

He needs the money.

Mike Tyson is reportedly set to star in a porn film - with Jenna Jameson. The former boxing World Heavyweight Champion claims he is desperate for cash, after being hit with a tax bill for several million dollars, and a porn career is a tempting offer.

I can't find anything definitively sourcing this, but it's certainly getting repeated a lot. Some of the outlets are more authoritative than others (though all of them refer to vague sources), but I find it odd that the one to specifically quantify Tyson's reputed endowment is Teen Today's gossip column.
