Tony Danza was one of the good actors of the 80s. His sitcoms that he played in, Who's the boss and Taxi was funny, but he just like so many another actors of those has-been 80s actors ( career after the 80s went downhill) that can't walk away from Hollywood and spends his time think about the FAME he once had.
Like so many others will do anything to keep himself in the glint and glimmer of it all and if that means making a fool of himself on TV, that what he'll do.
It's really sad to see people do this to themselves.
