I will tell you guys a crazy story about a beer bong. Mind you, this happened in college and I have not done a beer bong in probably 8 years. It was a fun thing from my past but I don't usually miss it.
So I had a friend named Michael that was pretty wild. He would try anything once and usually ended up doing it a dozen times. One time he rigged up a beer bong with a hose that stretched down three stories of a building. We had a friend in a third flood dorm so we set the beer bong up outside his window. Michael was lying on the ground outside with the end of the hose in his mouth. I was at the top with the funnel and a fresh 40 oz bottle of beer.
He said the whole forty rushed into his stomach in one big wave. He looked all right for about 30 seconds and then puked everywhere. It might sound stupid and pathetic now, but at the time I was rolling on the floor with laughter. Ah college, what a fun and silly time.
