A gorilla swaggered into a waterside pub, slapped a five dollar note on the bar and asked for a beer.

It took the barman by surprise for a moment, but ever ready to make a quid he capitalised on this unusual situation, pulling the beer, scooping up the fiver and giving the gorilla 60 cents in small change.

But as the primate sipped his beer, the phenomena of a talking gorilla aroused the barman’s curiosity to the point where it could be contained no longer.

“Out for a walk, are you? he ventured.

“Yeah,” mumbled the gorilla.

“We don’t get many gorillas in here,” pressed the barman trying to make conversation.

“No wonder, at $4.40 a glass!”
