Jim was in bed with his best friend's wife. Just as things were reaching a climax, he suddenly stopped and sat on the edge of the bed, holding his head in his hands.
"What the hell's wrong with you?" she asked.
"I feel just like a regular son of a bitch, getting some of my best friend's pussy," Jim moaned.
"Well," she soothed, patting his back, "you can stop worrying. You're not getting his pussy. His pussy is five inches deeper."
