A guy goes to the doctor and says, “Hey Doc, I know guys my age start to get hair growing in their nose and ears and stuff, but look at this.” Where upon he displays his penis which is covered with hair.
The doctor says, “Gee, never saw anything like that.”
“Am I in trouble?” asks the guy.
The doctor takes some samples and tells the guy to call him in a few days. When the guy calls the doctor tells him not to worry but advises him to, “Wash your hands better after you put the Rogaine on you head.”
