A man goes to Miami for a vacation. After four days he notices he has a tan all over his body, except for his penis. So the next day he goes to a deserted area of the beach early in the morning, takes his clothes off and lies down. He sprinkles sand over himself until all that remains in the sun is his penis.
Two little old ladies walk by on the boardwalk and one notices the penis. "When I was 20," she says, "I was scared to death of them. When I was 40, I couldn't get enough of them. When I was 60, I couldn't get one to come near me....and now they're growing wild on the beach."
