Can a Musical "Jump The Shark?"

I was just taking a lovely walk through Times Square and I saw a billboard for Tony Danza in "The Producers." I remember hearing about this but I never thought it would ever happen. You know when a musical has "jumped the shark" when they put in Tony Danza...of the failed and tepid "Tony Danza Show."

Danza is big on self promotion. I guess when he was in "View From The Bridge" on Bway he used to go personally hustle people to buy tickets to his show. I guess the producers are banking on tourists that really were into "Who's The Boss." I can't say if I think he is good in this part but if you are in NYC and want to check out Tony he will be in the part until March 11th.
