You gotta love this :D

Paddy and Murphy are on a building site.

Paddy says "I want a day off sick, I'm gonna pretend I'm mad".

He climbs up to the rafters and hangs upside down and shouts "I'm a lightbulb! I'm a lightbulb!"

The foreman shouts "You're fucking mad, go home!" So he leaves the site.....

Murphy packs up to leave as well.

The foreman says "Where the fuck are you going?"

Murphy says "I can't work in the fuckin dark can I ?
