Paddy and Mick hired a small boat from the local marina to do a spot of sea fishing, they were doing really well so Paddy said "we must come again tomorrow, you are the navigator Mick mark where we are." So in the pub that night Paddy said "did you mark the spot?" Mick says "ay I put a cross on the side of the boat" "bloody hell" says Paddy "we may not get that boat tomorrow!"
