Homosexuals

A group of homosexuals were attending a car-key party.

One bet the others that he could recognise the make and model of any car by sticking the ignition key up his arse.

The first key he correctly identified as a Ford Escort. The second as a Vauxhall Astra.

As a joke, one of the guests got a spark-plug and shoved it up his arse. Immediately he said, "Yes, that's Champion!"
