The Student Discount at the Brothel

A student comes to a brothel and says, “I want sex, but I’m a student, I don’t have much money.”

They tell him, “Okay, we have a special offer for students: it costs $1 to insert, $1 to pull out.” The student chose a girl, they went to the room. They got into bed, started. He put it in her and doesn’t move. She screams, “Pull out, pull out!” He replies, “I’m out of money.”
