They fixed it a few minutes before 1am but so you know I'm not crazy here's a video of when the cut back to history happened. www.youtube.com/watch?v=7mfFYALAOsY
I remember flipping through the guide early on a Saturday morning in 2008 and coming across Nicktoons. Well for a brief time it was the re-imagined nicktoons with the NHL Stanley Cup playoffs, and beer commercials. The hilarious thing about it was that the Nicktoons channel logo displayed on the channel the whole time on the bottom corner of the screen so it couldn't have been an issue with Dish Network moving transponders but rather an issue on Viacom's side.
