Henry Winkler had one of the great catch phrases in TV history on 'Happy Days' with "Ayyyyyyyyyyyy," Fonzie's exclamation for...well, lots of things. But does Winkler know other TV catch phrases?

He was on 'The Wendy Williams Show' (weekdays, check local listings) and she challenged him to a catch phrase-off. Let's just say that one of them wipes the floor with the other one.

I don't think Howie Mandel's catch phrase is "Don't touch me!" but it should be.
