Jim, my point is the recording of a joke, not just parodies.

All this boils down to is that there are people who like them and those who don't. You have to know your audience. I went to a session once and was asked to sing a parody right after someone had pointed out that one of the people present hated parodies. I was not inclined to sing it but others insisted and I sang it. There was no negative repercussions and the guy didn't walk out. I didn't feel too uncomfortable and even sang another later. But I made a point to limit the parodies I sang to just those two.
