....according to the New York Daily News, one possibility being bandied about would be to bring in another popular '70s-era icon who might play a brother to Ritter's bumbling dad, Paul Hennessy.
Already talk has centered on Henry Winkler for the job. The former Fonz from TV's Happy Days is an old pal of Ritter's and was scheduled to guest on the episode which the actor never completed due to his sudden death.
Other potential candidates could include sitcom vets Tony Danza, Howie Mandel and even Richard Kline, Ritter's Three's Company cohort.
