Oh, hahaha!
It's an inside joke from a while ago, back when me and some of my friends used TinyChat. The first time, my internet was weird and it wouldn't connect when I was trying to type in my username, so I just kept typing complaints until it worked, and ended up with the username "whyarentyouworking." That was too long for people to call me, so I ended up with the nickname why, which is, by the way, just about the most confusing nickname in the world. Eventually I found this picture and used it as my profile picture on skype and a few other places. When I was making my GC account, I looked in my saved images to see if I had any good profile pics and this was the only one I had saved and I was too lazy to make or find a new one, so there ya are! Not as many people call me why now, but it's still one of my favorite nicknames ever.
