A German, an American, and a Russian are arguing who can feed a spoonful of mustard to a cat more easily...
The German just grabs the cat and forces the spoon with mustard into its mouth. The other two protest: "This is violence!"
The American hides the mustard between two slices of sausage. The other two protest: "This is deception!"
The Russian spreads the mustard under the cat's tail. The cat starts furiously licking it off, meowing loudly.
"See - he does it voluntarily, and sings while doing it!"
