Tony's repetitive post reminds me of the fellow who went to the opera (first time) with a pal who was an
aficionado. Midway through Act I, the tenor sang a big aria that was coldly received (a few hisses, tepid applause). Our novice's friend shouted "ENCORE! ENCORE!," whereupon the tenor sang the aria again. Really badly.
The audience showed their displeasure by jeering, hissing and booing loudly. Once again, the same fellow stood and shouted,
"ENCORE! ENCORE!" Our newcomer was puzzled and asked his knowledgeable friend why he was so insistent on demanding repeat performances by this hapless tenor. The reply:
"I'm gonna make him keep singing it until he gets it right!"
