Joe Bravo

From Muppet Wiki

Joe Bravo is a friend of Waldorf's.

When Waldorf shouts "Bravo!" after a sketch in episode 210 of The Muppet Show, Statler mistakenly believes that his fellow heckler enjoyed the sketch. Statler corrects him, informing him that he is merely trying to get the attention of Joe, who is sitting in the third row of the Muppet Theater.
