Drunk recruit

Ah Seng, a recruit, was a bit of a loner. He took to drinking heavily whenever he booked out for the weekend. One weekend, he returned so drunk that he was told to see the Commanding Officer immediately. "Look Ah Seng, why don't you shape up?" said the CO, who was something of a softie. "There is a real future for you here if you sober up. You could become a corporal, or even a sergeant! Isn't that something to look forward to?" Ah Seng replied,"Well, Sir, to tell you the truth, that's really not good enough for me because after a few glasses of Tiger, I feel like a colonel!"
