Paddy and Murphy are working on a building site.
Paddy says to Murphy, ‘I’m gonna have the day off, I’m gonna
pretend I’m mad!’
He climbs up the rafters , hangs upside down and shouts:

‘I’M A LIGHTBULB! I’M A LIGHTBULB!’

Murphy watches in amazement!

The Foreman shouts: ‘Paddy you’re mad, go home’
So he leaves the site.

Murphy starts packing his kit up to leave as well.

‘Where the hell are you going?’ asks the Foreman.

‘Well I can’t work in the fecking dark!’ says Murphy.
