I offended someone with this:
I was in a pub and told the following joke:

What do you do if an epileptic has a fit in the bath?

Throw your clothes in so they get a wash.

Once the guffawing of my friends had died down, I became aware of a man on the other side of the bar, looking quite choked and talking to the landlord. The landlord came over to me and told me that the gentleman at the bar had recently lost his son and that my joke had offended him. I thought I should apologise. I approached the gentleman at the bar and offered my condolences for his loss and my apologies if my joke had upset him. He said that the joke had only got to him because his son was an epileptic and it was a fit which killed him.

I wondered as to how a fit could actually kill someone and the man said that his son had slipped and hit his head and that was what had killed him. I asked where his son had slipped and the man said it was in the bath. Well, I realised then how inappropriate my joke had been in the circumstances.

"Did your son hit his head on a tap then?" I asked.

"No," replied the man; "he choked on one of my socks".
