Perhaps my biggest (though not my first), without going into all the gritty details: a red-headed Cuban girl who I couldn't keep my friggin mind off her. Crushes are hard to explain. I don't know what it was about her (she certainly was SMOKING), but she was so much fun to be around that it drove me insane. In the end, she wasn't into me (after about 4 years I finally broke down and told her what was up) and that was that. I had to cut down all communication with her cus it would probably continue to drive me butt crazy.
@everyone - All I can really say is that I'm humbled by all your responses and wishes. It is your love and appreciation (as well as those of my colleagues) that has made these first three years so fun at DA.
