Two Irish builders are on a construction site, hammering floorboards down in a house.

Paddy picks up a nail, realises it’s upside down and throws it away.

He carries on doing this until Murphy says, “Why are you throwing those nails away?”

“Because they’re upside down!” says Paddy.

“You idiot,” replies Murphy “You should save them for the ceiling!”
