like most things context matters, honestly i can be very forthright about "embarrassing questions" or somethings. If among friends or if its merely about blunders or normal human behavior that is socially taboo I'm all game. If its about fessing up to social faux pas I've committed... well then I'm iffy whether I'll find it funny or not.
that's the main thing, will people laugh, embarrassment is only funny if everyone is in on the joke and finds it funny.,
