Okay then. The answer: Back when this wiki had "the" in its URL, there was another lesser-known Regular Show Wiki that used this logo prior to this one's adoption of it. As soon as I had become an admin for only half a year, I redecorated the wiki by transfering the logo from the not-so-known wiki to this widely known wiki. That initially had a backdrop based on what Cartoon Network was using for the games from the show in the US, then later uses the current one which is used for the show page here in America (and possibly Austraila), since that was.... well, matching, for a lack of a better word.

There's the answer, although it should have been on a seperate thread because this one is essentially the "Finnster/Viacom" thread from August 2013 which is an outdated thread.
