... of all subjects which are acceptable to the PC mafia as humour?
I mean, I'm a bit confused you see. We can poke fun at people with small willies but not people with big bellies. We can have a giggle at the expense of the French but not the Irish. We can ridicule the straight but not the gay.
Here's a challenge to the politically correct morons who are spoiling this site for the tolerant majority: Tell me a joke - any joke - that I can't pretend to find offensive. If you had a sense of humour you would realise that ALL humour is based on someone else's failure or misfortune and every joke you tell has a butt, you just don't like it when the butt is you, or when laughing would cost you points on the politically correct leaderboard.
Go on, tell me a guaranteed non-offensive joke and I'll throw it right back in your humourless face and see how you fucking like it!!!!
