As he sits down, he sees a very hot nun sitting near the back. He sits near her, and decides to put a move on her.
"Hey, you're pretty hot. Wanna have sex with me?" The nun screams and runs off the bus at the next stop, obviously very freaked out. The hippie, feeling defeated, decides to get off the bus as well.
The bus driver stops him as he's leaving and says "Hey, I saw you trying to get with that nun. She goes to this cemetery every Wednesday night and prays in front of this gravestone. Maybe, if you dress up like Jesus you can get her to do what you want." The hippie thinks this is a great idea.
So the next day he goes out and puts together a Jesus costume.
Wednesday comes around, and the hippie is hiding in the cemetery bushes. He puts on his Jesus mask, robes and a crown of thorns, and then jumps out in front of the nun.
"Ahhhh! I'm Jesus!" He says. "I will let you into heaven if you have sex with me!" The nun says " Hmmm...OK. But you have to do me in the ass so I can preserve my virginity."
The hippie agrees and says, "No problem, sister!"
So, they start going at it, and the hippie decides to give the nun a little surprise. So he pulls off his mask and yells "Surprise! I'm the hippie from the bus!" The nun pulls off her habit and yells "Surprise! I'm the bus driver!"
