There is a nun and a hippie on a bus.

The hippie asks the nun "will you fuck me?"

The nun replies "no!"

So the nun gets off the bus and then the bus driver says "I know how you can get in that nun. You go to the cemetery tonight at midnight and come dressed as god because shes there worshipping her god."

So the hippie goes to the cemetery and has sex with the nun.

After the sex the hippie rips off his mask and says "Ha! I'm the hippie"

The the nun rips off her mask and says "Ha! I'm the bus driver."
