Haha #1 is my favorite.
Here's my 3:
#3 - Family reunion: The reunion didn't start until about 6pm and I thought it would be a good idea to start about 11am...bad idea. After about 15 beers and an hour car ride we arrive at the fiesta and my uncle immediatly greets me with a bottle of crown royal (typical crazy uncle) and says "you ready". Last thing I remember is having to leave the karaoke stage mid-song to

and my whole family pointing and laughing at me. Had to stop three times the next morning on the side of I-35 to well...you know!
#2 and #1 are from college days.
#2 - Frat Party: The The University of Texas here in Austin theme parties are a big deal. I took a date to a large full-camo themed frat-party...face paint and everything. After about 9 hours of beerbonging, shotgunning, and shot taking I woke up to find my self in an all girls dorm during "breakfast call." Since I wasn't supposed to even be in the building I literally had to run through the cafeteria while 500 girls stopped and stared. I looked like I had done 2 tours of duty in vietnam.
#1 - House Party: I was kindof a good beerbonger back in the day. One night instead of beer I was dared to bong bacardi rum and I did. I bonged around a half-bottle with about an ounce of coke in it. I woke up the next morning(luckily) to two black eyes, a bloody nose, and a fat lip. My buddies told me I passed out standing up and came crashing down on the concrete face first

.
I'm so glad those days are behind me.
