A salesman was testifying in his divorce proceedings against his wife.

"Please describe," said his attorney, "the incident that first caused you to entertain suspicions as to your wife's infidelity."

"Well, I'm pretty much on the road all week," the man testified. "So naturally when I am home, I'm attentive to the wife." "One Sunday morning," he continued, "we were in the midst of some pretty heavy lovemaking when the old lady in the apartment next door pounded on the wall and yelled, 'Can't you at least stop all that racket on the weekends?'"
