One cold December day, a Scottish tourist in France decided to find out if the natives were as tight as he had heard. He stopped at a house, told the woman of the house he was freezing to death, and was invited to come in and warm himself at the hearth.
Once inside, he complained of being thirsty. The woman handed him an enormous white crockery mug filled with milk. After taking a big swig, the impulsive guest exclaimed, "This is sweet and fresh ... you are most generous!"
She replied modestly, "It's nothing. My family wouldn't drink that milk because we found a dead rat in it."
Sick to his stomach, the Scot clapped both hands over his mouth, allowing the huge mug to fall to the floor and shatter on the stone.
The Frenchwoman grabbed her broom, raised it high in the air, brought it down on the visitor's head, and hollered, "Get out, you ungrateful pig! I take you in my home, I let you share my fire, I give you milk to drink ... and now you repay my kindness by breaking the children's potty!"
