Notes:

The art of UG you see right here is by the show's creator himself. Apparently CN sent out some kind of statement making it sound like Uncle Grandpa had been picked for a 4th and 5th season, but it turns out the whole thing was worded in a really shady fashion and the reality is the 4th and 5th seasons have been cancelled, and the UG staff is being laid off from Cartoon Network.

Whether you like Uncle Grandpa or not, this honestly feels like some pretty shady stuff on CN's part, especially if it's enough to make the show's own creator draw a picture of his creation about to shoot himself in the mouth.
