A monk who's been sheltered all of his life has to travel to the big city to meet his friend, a Catholic nun.

On the streets of the city, he encounters a prostitute, who says: "Blowjob? Five dollars?"

"No, thank you!" the monk says, blushing.

He moves on to the next street corner, and another hooker asks him, "Blowjob? Five dollars."

He hurriedly rushes down the streets, but on each corner, there's a woman asking if he wants a blowjob. By the time he reaches the convent, he's very upset.

He asks his friend the nun, "Sister, what's a "blowjob?"

She smiles and replies: "Same as in town, five dollars."
