Paddy & 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 & 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. 'I cant work in the friggin dark! ' says Murphy.
