What happened to waiting guests when they ran out of time?
The mystery guest was almost always the second to last guest, yes? And then there was usually one more guest afterward.
But sometimes the mystery guest stumped the panel and went until the end of the show. I've always assumed that there is a guest waiting in the wings who didn't get to appear.
Were they invited back for the next week's episode? It seems that they should have been... my only concern would be if the guest was from out of town. Would they be expected to go home and then fly back to New York? Does anyone know?
