Kitty-Kill Condition

"Kitty-Kill Condition" is an episode of The Itchy & Scratchy Show.

Plot
Scratchy goes into the office of Dr. Itchy, the Feline Cardiologist. After Scratchy fills out a medical questionnaire, Itchy has Scratchy get onto a treadmill for a stress test. While he monitors Scratchy's heart rate, Itchy increases the treadmill's speed, tilts the ramp so that Scratchy is running uphill, opens a trapdoor behind Scratchy revealing a group of hungry crocodiles, and adds a series of flaming hoops to the ramp, which Scratchy has to jump through. All the while, Scratchy's heart rate becomes even faster, until the flaming hoops prove to be too much and Scratchy suffers a heart attack and collapses.

Itchy then puts Scratchy onto an operating table, cuts his chest open, and removes his heart. The heart escapes and runs on its own all over the treatment room, leading Itchy on a chase until he catches up to it and jams a lit stick of dynamite into it. Then Itchy puts the heart back into Scratchy's chest and sews him back up. When Scratchy wakes up, Itchy shows him a picture of himself (Itchy) in bed with Scratchy's wife. The sight causes Scratchy to suffer a final heart attack, which is fatal.

The scene then shifts to Scratchy's funeral with his wife, son and the rest of his family attending. The dynamite Itchy put in his heart explodes during the graveside service, killing all of the mourners.
