This is a classic Itchy and Scratchy episode from the simpsons. If you're a simpsons nerd like me, you'll remember what episode this is from. If you're not, it's from the one where marge gets all pissy and protests against Itchy and Scratchy.
Oh yeah. I remember that episode where Marge took a stand against Itchy & Scratchy for it's gory violence since Maggie hit her father in the head. It's like she's listed under Moral panic's category on Wikipedia.
