Hoooo boy, now THIS is a question I expected even LESS. A few years ago, between season one and two of MLP:FiM, there was a joke-news on Equestria Daily, and the comment section of it quickly derailed into an RP thread. Me and Slots took part in the RP, and in a matter of a few DAYS we hit the comment cap (the old blogger system had 5000 limit), so we started to move somewhere else. But anyway, I got to know him from that RP, we started to talk a bit through email (I think?) and then moved on to Skype. And well, then it just developed into the best friendship I ever had.
