In The Desert

There were two men walking in a desert, one with an umbrella, the other with a car door. They just so happened to bump into each other one day. The man with the car door asked the man with the umbrella " My friend, why do you have an umbrella in the desert, it's not like it's ever going to rain." to which the man with the umbrella replied " True, but if I ever get too hot, I can just open up my umbrella and it will shade me from the Sun" He finished his response to the other man with the question " Why are you carrying around a car door, it's not like you're getting anywhere any faster" the other man replied "True, but if I ever get too hot, I can just roll down the window and let the cool breeze in."
