Besides a few bruises and scratches from falling down stairs or bumping into things, I have not had any major injuries. One of my sorority sisters on the other hand....
She got really drunk one night at a party in our friend's apartment. A bunch of us were out on the balcony and she wanted to join us. She didn't realize that the glass sliding door to the patio was closed. She went plowing right into it and broke her toe. We were all laughing so hard because we heard this huge thud against the glass sliding door and we look over to see her lying on the floor. Glass sliding door took her out! She had a fun time trying to explain that one to the doctors and her parents the next day.
Another time, my friend fell off the bar and broke her ankle. I think I talked about that on here in the drunk thread.
