"I'm sorry but I've given my body to God," she replies and then leaves. The bus driver turns to the guy and says, "I know a way you can get her in the sack."
The bus driver tells the guy about the nun's daily 3PM confession. The bus driver tells the guy his plan and the guy leaves happy and excited. The next day at three the guy is in the booth dressed as a priest.

After it is over he whips off his outfit and says, "Surprise, I'm the guy on the bus." With that the nun turns around and says, "Surprise, I'm the bus driver."
