Evil Stephen Colbert appeared on The Colbert Report (of our dimension) on 2nd Oct 2007 when a quantum truthic phenomenon allowed broadcast signals from that parallel universe through to our universe in our point in truthic space time. Anti-Colbert spread evil defeatist ideals like "Troops Out Now" nonsense.
With amazing coincidence, Evil Stephen Colbert also happens to be a host of The Colbert Report in the parallel dimension. Moreover, he has a The Word segment with a peace sign in place of the 'O' in 'word'. Anti-Colbert has a goatee and is a recreational drug user.
