Funny story actually. I was looking up ExplosiveBubbleWrap in google images, and it naturally brought up almost everyones avatar in BB who used some sort of website to make theirs that saved it because ExplosiveBubbleWrap was instantly connected with buzzerbeater due to the unique name. Your avatar was on there to. I thought it would be funny to have the same one as somebody and since hrudey and I are both so active in the forums, I thought it would be interesting to confuse some people. No harm intended, I promise.
