There was a man who went to a restaurant and ordered some food. After receiving his order, he suddenly called to his waitress and said, "Please, come here." When the waitress came, he showed her a potato on his plate and said, "This potato is very bad." So the waitress picked the potato up, spanked it, put it back down again and told the man, "Sir, if this potato makes any more trouble for you again, just call me."
