This is a true story. If you have children you will probably relate to this.
father:
As ham sandwiches go, it was perfection: a thick slab of ham on a fresh bun with crisp lettuce and plenty of expensive, light brown gourmet mustard. The corners of my jaw aching in anticipation, I carried it to the table in our backyard and picked it up with both hands but was stopped by my wife suddenly at my side. Here, hold Johnny (our six-week-old son) while I get my sandwich,"she said. I had him balanced between my left elbow and shoulder and was reaching again for the ham sandwich when I noticed a streak of mustard on my fingers. I love mustard and had no napkin so I licked it off. It was not mustard.
No man ever put a baby down faster. It was the first and only time I have sprinted with my tongue protruding, with a washcloth in each hand I did the sort of routine shoeshine boys do; only I did it on my tongue. Later, after she stopped crying from laughing so hard, my wife said, "Now you know why they call that fancy mustard . ."Poupon."
