Checking the menu, a restaurant customer ordered a bowl of vegetable soup.  After a couple of spoonfuls, he saw a circle of wetness right under the bowl on the tablecloth.

He called the waitress over and said,

"It's all wet down here.  The bowl must be cracked."

The waitress said, "You ordered vegetable soup, didn't you?"

"Yes."

"Maybe it has a leek in it!"
