Haha...I have a few from my year. I'm not going to use anyone's name to protect the innocent though...
I went back to my room with one of the girls and unfortunately, my roommate and some other guys were aware of that. My roommate (who I ended up running with in college) tried to come in using his key, but I had obviously latched it shut so eventually he gave up. The girl and I got down to business and then out of nowhere, my buddy from my home state comes barging in through the damned sliding glass door. We were on the 4th or 5th floor and this clown literally climbed over from the adjacent balcony. Needless to say, she ran out and that was the end of that.
For those of you who haven't been, the Nike reps bring a truck load of gear. Everyone gets their allotted amount, but there's literally a room full of extra stuff. The kids all try to get buddy/buddy with the reps so that they can get extra stuff and the reps will literally give out tons of extra stuff to the kids they like the most. One of the girls (a current/former American record holder) and I decided we didn't want to have to kiss their asses, but we also wanted extra stuff to take home to our friends. So the Nike reps room was on the first floor so she decides we'll just go in through the sliding glass door and much to my surprise, it was open. We proceeded to "shop" for a few minutes and then we heard voices outside. I grabbed all the stuff and literally dove out the door with her right behind me. We shut the door at literally the same moment the rep came in through the front door. I think I ended up with an extra pair of spikes, a few t-shirts, and a warm up suit for my coach. Considering one of the guys I knew had to buy an extra suit case to carry home all the extra stuff he got, I've never felt very bad about it.
Funny story from a different meet...Golden West invite is a pretty good source for stories. I don't know if it still happens or not, but there was a naked mile my year with an abundance of attractive girls participating. (pretty sure the then girls national record holder in the 3200 was there) Unfortunately, the sprinters showed up and stole all of our clothes. I threw on a soon to be fairly famous girl's running shorts and chased down a future All American in the 100m (I think he was barefoot) to get my shorts with my wallet back.
I'm sure there are a few others, but nothing else great comes to mind off the top of my head. If I think of anything else, I'll come back tomorrow.
