Please will someone explain the rape joke!
I just don't get it and that's annoying me now!
You mean the Joe Lycett one? He says he saw an absurd scenario involving two species of animal, one sexually attacking the other, and found it funny, and then the punchline was to say that all rape is funny if you think about it.
I think the idea is to illicit awkward laughter, a la Jimmy Carr as in "You can't say that!" while feeding off the darker elements in some of your audience.
Rape isn't funny. Anyone who tries to draw near the knuckle humour from a rape scenario is usually inverting the power balance to press the absurd, which I think is what Lycett was going for, but it doesn't work. He's just showing how he doesn't like women.
