drink 1 gallon of milk in 1 hour. I have yet to attempt this, but serveral of my friends have, and none have been able to do it. From what i understand it can be any milk (whole, 2%, 1%, skim), and the only stipulation is that you finish the whole gallon in 60 minutes without vomitting.
To me, it seems like it would be a pretty easy task...but since i know 4-5 people that havent been able to do it, i figured it's worth a shot to see how many people on this board would try. i'm going to attempt sometime this week.
