what do you if you see an epileptic having a fit in the bathtub?

Throw your washing in.
Now having told this joke in a pub the other day a bloke politely tapped me on the sholder and said mate thats not funny my son died having an epileptic fit in the bath.
Mortified all i could say was Im sorry mate drownings a horrible way to die.
To which the bastard replied oh he didnt drown he choked on one of my socks.
