One day a hippy is getting on a bus as a very attractive nun is leaving it. As he walked to his seat he said out loud to himself, "I want to have sex with that nun"

The bus driver hears and says, "She will only have sex with God, she goes to the graveyard at 12pm everynight, go dressed as God and she will have sex with you.

So the hippy turns up as advised disguised as God with a white beard and toga on. The the nun says "Can you give me anal as i dont want to lose my virginity". The hippy is more than happy to go along with this.

When they have finished the hippy says "haha I'm the hippy from the bus earlier", to which the nun replies " haha im the bus driver".
