Bloke's wife is pregnant and suddenly gets the craving for snails. So she demands,
"Go to the French restaurant and get me a large portion of snails. Don't go to the pub,and come straight back."
So off he goes, but on the way back he passes the pub and thinks 'she will never know if I only have one'.
Four hours later he staggers home, falls over the dustbin and makes a loud racket and the snails are scattered all over the floor.
His wife appears at the door with a rolling pin: "WHERE HAVE YOU BEEN?"
"Come on lads, not far to go now."
