Challenge them to eat 6 premium plus or similar salted crackers in a minute without the assistance of drink. Sounds easy but your mouth will dry up fast, only seen one person i know do it.
i could probialy do it.. but a better thign to do to your drunk passed out friends is to put a big book on their lap and light it on fire with the assistance of lighter fluid of course... trust me you;ll laugh your ass off its soo god damn funny
i donno if this adds up to a gallon, but me and my friends call that the gallon challene. gallon of milk in under an hour. we did it on a sports trip last summer and every kid threw up or couldnt finish.
It is a gallon of milk, Dizzle did it on that Inked show... I thought about doing it, divide the jug into 6 equal parts, (just mark it off with a marker) and drink each of them over 10 minutes. or 5 minutes, with a 5 minute break in between.
last night me and some friends was on a late night joy ride (really high) and we stopped at the store and i drink a half gallon of chocolate milk in under 15 minutes i thought i was gunna puke.
me and a friend did the milk one to see who could hold the most, but we did it in half pint cartons of milk. i got to 21, and he got to 22, then we both sat in the bath room for about 2 hrs. neither of us puked, but we both were at the state fair for 4h, and he had a cow there, so we are pretty tolerant to milk.
