I was sitting on a bus with a friend and he told me this joke...

What do you do if you see an Epileptic having a fit in the bath?

- Throw in your laundry.

The guy behind us leaned over and said "I think that's disgusting. My son died in the bath whilst having a fit."

We both went white and apologised. The guy got up to get off and said, "he choked on a sock."
