It's clearly a joke that Uncle Grandpa has visited past CN characters. And besides, a few of the shows have ended in the past, one of them recently got a reboot, and a few of them are still airing today. This episode was just a huge joke, because Uncle Grandpa first aired on September 2, 2013. There's no way he visited old CN stars.
