In one of the revival series' best changes, Dan Butler's Bob 'Bulldog' Briscoe has made his grand return to Frasier but not as fans might remember him.

Barney Martin famously played Jerry's dad on Seinfeld, but hardcore fans know he was the replacement of another actor who had the role for one episode.
