A man went into a restaurant

A man went into a restaurant for lunch and ordered soup, mashed potatoes, milk, and coffee. When the waitress brought him the coffee she had her thumb in it, but the customer was too polite to say anything. Then she brought over his milk with her thumb stuck in the glass, and the same with his soup. Finally she served his meal, her thumb buried in his mashed potatoes, and he couldn't keep quiet any longer. "I hate to embarrass you," he said politely, "but when you served my coffee you had your thumb in it, and the same with my milk and soup and mashed potatoes."

"I know." said the waitress. "I have an infected thumb and the doctor said I should soak it as much as possible."

"That's revolting, " said the customer, thoroughly grossed out. "Why don't you just stick it up your ass?"

"Oh, I do when I'm in the kitchen."
