Rosy, posing thoughtfully in the mirror, says to Nina, "I think I'm going to see a dietitian."

Nina asks, "Why?"

Rosy answers, "'Cause I need to know once and for all how many calories there are in semen."

Nina replies, "I really have no clue, but if you're swallowing that much of it, no guy is going to care if you're a little chunky."
