Jon left for a two day business trip to Chicago.  He was only a
few blocks away from his house when he realized he'd left his 
plane ticket on top of his dresser.  

He turned around and headed back to the house.  He quietly
entered the door, walked into the kitchen.  He saw his wife 
washing the breakfast dishes, wearing her skimpiest negligee.

She looked so good that he tiptoed up behind her, reached out, 
and squeezed her left tit.

"Leave only one quart of milk," she said.  "Jon won't be here for 
breakfast tomorrow."
