"My Bloody Valentine" is the Valentine's Day episode of The Itchy & Scratchy Show.
Plot[]
For Valentine's Day, Scratchy gives Itchy a heart-shaped card that says "I Love You." Itchy pats himself down looking for something to give Scratchy in return, and when he finds nothing, he punches a hole in Scratchy's chest, rips out his heart, and gives it to him as a present. Pleased, Scratchy goes home, puts the heart on his mantelpiece, and sits down to read the newspaper. Scratchy then sees a headline reading "You Need a Heart to Live." When this sinks in, Scratchy gets up and frantically tries to get to the mantelpiece to put his heart back in his chest, but dies before he can reach it.
