It's a one-night stand. The couple has just finished having sex. The man kisses the lady and says, "I'd love to stay, but I bet your husband will be coming home anytime now."
"Husband?!" the lady asks. "What makes you think I have a husband?" The man says, "I couldn't help but notice the picture of that man on your nightstand." The lady laughs and replies, "Oh, don't be silly. That's just me before the surgery."
