The Question

The Question, similar in design to the Balloon-Head Conductor is a purple tuxedo-clad character with a pink balloon for a head. The Question's balloon head appropriately has a big question mark where its face should be.

In the At the Dance sketch on episode 115 of The Muppet Show, George the Janitor asks Mildred Huxtetter if he can pop The Question, and then he does.
