Zuzu Fitzwaller is a Hungarian water juggler in The Muppet Show episode 406. Zuzu was booked as the opening act of the episode, but Miss Piggy tells him to go home, to make way for her salute to Kermit's birthday.
A tearful Zuzu pours out his sorrows to the frog, pointing out that his act involves juggling an entire bucket of water, and that his girlfriend Gloria came all the way from Pittsburgh for the occasion. Kermit takes pity and reinstates him, only for Piggy to give the liquid juggler the axe yet again.
Mr. Dawson, Kermit's old acting coach, gives Zuzu pointers on how to cry properly.
