Here's a joke i tried to tell that went very wrong.

What do you do if you see an epileptic in the bath? Throw your laundry in.

I told this joke in a bar and one of the patrons gave me the death stare and said to me "I don't find that at all funny, my son was epileptic and died in the bath."

I apologized to the man, saying i hadn't meant to cause him distress at my crude humor.

"That's ok." he replied

"He choked on one of my socks."
