An Englishman, Welshman, Scotsman and an Irishman
were all sitting down discussing what is the fastest thing in life.

After a few moments Paddy cut in," I believe you all
have valid points but I think Diarrhoea wins!"

"What the hell ! are you talking about, Paddy?"
chimed the three other guys.

"Well it is like this. Last night I went down to the
local curry house for a vindaloo, which I washed down
with 12 pints of Guinness, I then retired to bed.
However at 3 o'clock in the morning, before I could
