Hippy and the bus driver

So a hippy gets on a bus and sees a beautiful nun sitting there. He tries to talk to her but she refuses saying she has devoted her life to god only.

The nun gets off at the next stop and the hippy decides he wants to have sex with her. The bus driver, seeing the hippy perving on the nun, waves him over. "I see you like her... I can tell you how you can have her. I know she goes to the cemetery every Tuesday at midnight to pray to god. If you dress up as the lord she will surely do the deed, after all she has devoted her life to god"

So the hippy waits until Tuesday midnight and puts on a beard and flowing robes. He sits behind a headstone and waits for the beautiful nun to come by. He sees her kneel down to pray and leaps out saying "I am the lord and I will grant your prayers if you have sex with me first"

The nun is a little startled but replies " well alright but we'll have to do anal as I'm saving my virginity". So they do the deed and as they finish the carnal act the hippy rips his beard off shouting "Aha! I'm the hippy!!"

To which the nun pulls off her habit shouting "Aha!!! I'm the bus driver!!"
