Reminds me of:

A priest and a gentleman were sharing a compartment on a European train on a hot summer day before AC was common. The priest was wearing his black cassock and the gentleman, a nice suite. The gentleman took off his jacket, looked at the priest and said, "I bet you wish you could do that." The priest excused himself, and returned a few minutes later, carrying his pa*ts over his arm. He looked at the gentleman and said, "And I be you wish you could do that!"
