I'm not too graceful myself. I am forever finding new bruises that I don't remember getting.
I have one occurrance that always sticks out in my memory as my "most graceful". I may have had worse, but this one is the one I remember.
I went to college at SUNY Buffalo. It's a HUGE university with enormous 100 and 200 level classes. There were two lecture halls in this one building that look identical, and they're pretty close together, so if you're not really paying attention, it's plausible that you'd go into the wrong room. Well, this one day I walked into the hall through the door at the top of the auditorium, and started walking down the stairs to try to find a seat. I noticed that there were a heck of a lot more men in the class than would seem normal for a psychology lecture. Then I looked at some of the text books and realized I was in an engineering class. I didn't want it to be obvious that I had messed up and was in the wrong room, so I tried to be cool and subtley just walk out the door at the bottom of the lecture hall (which is right in the front of the room, so there could have potentially have been hundreds of eyes on me). I was wearing boots with high heels on, and when I opened the door to step outside, my heel got stuck and I tumbled out the door. The door closed, but not before I could hear the sniggers of quite a few engineering students.
So much for being cool.
