The Circus owner went to the pub for lunch. He got chatting to
the barman about his job. "Well I've got news about the best act your

more, he works as an electrician on the building site over the road"
The circus owner hurried over to find the horse in a pair of overalls, holding a coil of wire. "Why don't you join my circus" said the owner, "I've got a wonderful troupe, lions, tigers, acrobats and clowns, but YOU would be the top of the bill."
The horse thought for a moment. "I don't understand" he replied, "why would you want an electrician to be the top of the bill?
