A Rabbi a Priest and a Pollock met in the Sahara desert. The Rabbi asked the Priest, “what are you carrying?” I have a bag of bread. If I get hungry, I have something to eat. The Priest asked the Rabbi, “what are you carrying?” I have a jug of water. If I get thirsty I have something to drink. They both look at the Pollock. He is shlepping a car door. They asked the Pollock, “why are you shlepping a car door through this desert?” Well, if it gets too hot, I can always roll down the window!
