A priest and a nun are driving in a car towards a monastery, priest behind the wheel.
Approaching the red light, priest places gently his hand on the nuns knee to which the nun looks at him and says, “Father, remember Luke 14:10”. Priest apologies, removes his hand and keeps on driving.
At the next red light, priest again places his hand on the nuns leg, slightly higher than the last time. To which the nun awkwardly repeats: "Father, remember Luke 14:10".
Priest promptly removes his hand, apologies and mentions how his desires are stronger than his restraint.
When they finally reached the monastery and said goodbye, priest went to his room, immediately picked up the Bible and looked up Luke 14:10.
