The German Territorial Defense decides to call up some animals who should be fit for reconnaisance purposes. So the hare, the fox and the bear get their letters to report for their medical examination.
But since they do not want to join the army, they are guessing how to avoid it.
Says the fox to the hare: "Let's cut off your long ears. No ears, not a hare, no service." So they do, and the hare comes back and says: "Unfit - No ears, not a hare, no service."
Now it's the turn of the fox. Says the hare to the fox: "Well, let's cut off your tail. No tail, not a fox, no service." So they do, and the fox comes back: "Unfit - No tail, not a fox, no service."
But what to do with the bear? The others say: "Let's break out your teeth. No teeth, not a bear, no service." The bear comes back and mumbles: "Unfit for military service - too thick."

Had to tell any joke, not letting stand the contribution before on this ominous date.
