An Israeli soldier who just enlisted asked the Commanding Officer for a 3-day pass.
The CO says "Are you crazy? You just join the Israeli army, and you already want a 3-day pass? You must do something spectacular for that recognition!"
So the soldier comes back a day later in an Arab tank!
The CO was so impressed, he asked "How did you do it?"
"Well, I jumped in a tank, and went toward the border with the Arabs. I approached the border, and saw an Arab tank. I put my white flag up, the Arab tank put his white flag up. I said to the Arab soldier, "Do you want to get a three-day pass? So we exchanged tanks!"
