"Honey, we're moving!"

"Why?"

"We just have to move from this building!"

"But we just moved here two months ago."

"I know, honey," the husband nodded, "but I just found out a terrible piece of news."

"What?"

"The janitor had an affair with every woman in the building except one."

"Humph!" said the wife, "that must be the stuck up Mrs. Klian on the third floor."
