I don't remember the exact date, but it was at least five years ago I remember seeing an episode of Courage the Cowardly dog on cartoon network that was way too violent to be shown on kids programs.
The episode begins with Courage waking up, stretching then walking downstairs to find Eustace sleeping on his chair, meanwhile Murial is cooking, Courage yawns then there's a knock on the door.
Its a mountain goat wearing a top hat and monocle, "Good' day fine dog, may I stay for a night, I require rest for my big day." Murial comes to the door but the goat comes in before anything is said.
Eustace has now awoken and was complaining at the goat, the goat simply replied with "Fuck you."
Which I was rather shocked about. I paused it for a second before listening again.
Courage is already suspicious as the goat. he then went upstairs into the bedroom, Courage follows him, and the goat starts chanting continuously then an axe appears on the floor and the goat picks it up then disappears, Courage does his usual scream then runs down stairs.
But when he reaches down stairs he looks out of the window to see that its night already, Murial and Eustace were now sleeping, then Courage grabs them by their hand and drags them into the cellar, then pulls out a giant lock, then locks and chains up the door.
A cockerel is heard and all of a sudden its morning, the goat suddenly appears behind Courage and says "Its my big day!"
Courage gulps and suddenly the goat starts chasing everyone with the axe, Eustace awakes and shouts "Fucking dog and goat."
Then he tries to kick the goat but the goat ends up chopping of his foot. Eustace falls down and lets just say, what the goat did was not pretty but it ended up chopping of Eustace's head!
Then the screen went static and the whole show stopped. I figured Cartoon Network had managed to stop it from being aired.
