Tricky - I tend to be fiercely loyal beyond the point of reason or rationality, whether it be people, places, things ("so I unpacked my adjectives") or music.
"Have Some Madeira, M'Dear"
by the Limelighters struck me as very funny as a kid. As an adult, I realized that it is, technically, about date rape, hence much less funny.
Interesting how much the world has changed - in the sixties, a group that encouraged brotherhood, etc. got laughs with a song like this. As a history teacher, I get the humor, but it's a lot more creepy now.
