How about the triathlon:
1/3 Gallon of Whole Milk
1/3 Gallon of Chocolate Milk
1/3 Gallon of Egg Nog
all in an hour
I had a cement mixer when I was wasted once, dont remember it being that great.
The worst is the prairie fire - tequila and Tabasco sauce shot. I bought some chick I knew one on her 21st birthday, I took one with her. She puked it right back up haha.
