"The Secret Garden" - late in the run, and I didn't much care for the lead girl. At one point her father is talking about sending her away to school and says something like, "It should be somewhere where she can learn to sing and act" -and I guffawed. Then realized that it wasn't meant to be a joke and slunk down in my seat...
Or "Saturday Night Fever" from the 3rd row, spent mostly hiding behind our Playbills trying to hide our sarcastic laughter from the cast (who could clearly see us- and it wasn't their fault the show was ludicrous). But when those mirrors began to close in on Paul Castree as he sang a slow heartfelt reprise of "Tragedy" (a tragedy, because his pregnant girlfriend wouldn't get an abortion) I think we nearly ended up on the floor.
"What- and quit show business?" - the guy shoveling elephant shit at the circus.
