I got a platoon mate back then in my army days called Winston Chan and he has always been known as a fast drinker who can glup 1 litre of water (the green army bottle) down in less then 10 seconds. He performed this talent of his a few times in front of our platoon, the most recent one during the ict not long ago. Well, we considered that crazy enough already.
However, Winton if you happen read this, I am sorry to tell you that your record has been broken. Some crazy japanese guy did a 1.5 litres in 4.88 secs.. Crazy shit, i still cant believe the entire 1.5 litres went down. Neither did the audience, who were equally stunned. Check out the "wtf" look on their faces at the end of the clip. Hilarious!
