An unemployed actor was looking for a job, he saw an advert for a temporary acting job at the zoo. On arrival he was interviewed, and told there was a vacancy for a gorilla, due to the unfortunate sickness of the real gorilla. He agreed to take the job, which involved dressing up as a gorilla to entertain the public till the real gorilla was well again.

Getting into his stride, he started swing energetically on the branches of the tree, only to overdo it and fly into the lions cage. Seeing the beast advancing he began screaming for help.

The lion said "Shut up for gods sake or you will get us both fired"
