Don’t do it Tiger. You will become more of a laughingstock and in the end, any such confession will come back to bite you ever-so-deeply in the buttocks and the wallet.
Maybe he considers saving his marriage more important than his reputation or wallet?
He wouldn’t be the first guy that realized what he was about to lose his wife and children and came to his senses. A few flings? Money? At the end of the day those things pale in comparison to your family (including your wife.)
Not that he needs my advice but I say, don’t do it. Exposing it all on TV is sooo over.
