A man was sunbathing in the buff at the beach. For the sake of civility, and to keep it from getting sunburned, he had a hat over his private parts.
A woman walks past and says, snickering, "If you were a gentleman you'd lift your hat."
He raised an eyebrow and replied, "If you weren't so ugly it would lift itself".
