1) Been Arbor Day Queen.
2) While in a foreign country, been accosted by a drug dealer, rescued by a friendly concerned citizen, and had no idea what was going on until someone English-speaking had time to explain it to me half an hour later.
3) Convinced an absent gamer, calling in to find out what was going on in the game, that his character was in combat with a Balrog. Before I was potty-trained. (And with much prompting by an amused and sadistic gaming group, admittedly.)
Possibly some of the academic achievements from high school, but given my friends, I wouldn't count on it. I can think of some interesting things I did with people on my friendslist, but very little that is unique.
I hope I'm forgetting something. I hate to believe that I'm really that boring.
