Checking the menu, Paddy, a restaurant customer, ordered a bowl of soup.
After a couple of spoonfuls, he saw a circle of wetness right under the bowl on the tablecloth. He called over to the waitress and said,
"It's all wet down here. The bowl must be cracked."
The waitress said,
"You ordered the vegetable soup, didn't you?"
"Yes," Paddy replied grimacing
"Well, maybe it has a leek in it!", suggested the waitress.
