When someone's elbows become so dry they become rough and scaly. Some common causes are eczema or psoriasis.
Person 1: OW! Your elbow just scratched me! Do you have sandpaper on it or what?
Person 2:Why would I wear sandpaper on my elbows?
Person 3: I can answer this question. You have alligator elbows.
