6. Billy – WHO’S THE BOSS
I don’t know what Tony Danza was smoking when he decided to add little Billy to the show. The back story for the character was that he was the grandchild of some old broad that Tony was close to back in the day in Brooklyn; the old biddy became gravely ill and no one was around to take care of the wide-eyed, precocious little devil except for Tony. So in Season 7 of WHO’S THE BOSS Tony and Angela took a break from their “will they or won’t they” relationship and instead became surrogate parents for an awful little kid that tried too hard to be cutesy. Danza, being executive producer on the show, realized the huge mistake he made and by the next season Billy was shipped back to his granny in Brooklyn and the show went back to focusing on the Tony/Angela romantic relationship.
