I guess it's a version of the "know-it-all" but how about the people walking out of the show explaining all the reasons that the show wasn't as good as (insert date) that they saw. Or if he had just sung (insert title) that he sang when (see date above), etc., etc., etc.then it might have been OK ??? And some fat bald character talking about how "he's gotten old hasn't he"??
They should let us screen these people, LOL
