Mad Wife Disease

He was sitting quietly reading his paper when his wife walked up
behind him and whacked him on the head with a rolled up magazine.

"Ouch!! What was that for?" he asked.

"That was for the piece of paper in your pants pocket with the name
Mary Lou written on it," she replied.

"Two weeks ago when I went to the races, Mary Lou was the name of one
of the horses I bet on," he explained.

"Oh honey, I'm so sorry," she said. "I should have known there was a
good explanation."

Three days later he was watching a ball game on TV when she walked up
and hit him in the head again, this time with an iron skillet, which
knocked him out cold.

When he came too, he asked, "Now what was that for?"

She replied, "Your horse called".
