One doctor puts Jof on a treadmill, then turns up the speed and angle to insane levels. Bruno Bozzetto's short cartoon Help? has Jof the cat visit a hospital for a sore finger.Exaggerated in the Futurama episode "Reincarnation", where Fry's heart pops out so far that it keeps hitting Bender in the back until it comes out of Bender's chest.He even literally crosses his heart as he promises to help her. Droopy experiences this in the Droopy, Master Detective episode "Shadowman and the Blue Pigeon" when a beautiful mysterious lady flirts with him.He finally figures out the ruse shortly after the toy jumps out from under the blanket. This includes sneaking a little toy rabbit that's attached to an air pump under his blanket and pumping air in various ways, making Donald think his heart is acting out this trope and he's done for. Spoofed in Donald's Off Day when Donald Duck's nephews trick him into thinking he's terminally ill.In the Cow and Chicken episode "Stay Awake", in which Chicken starts acting out of control after eating a bowl of coffee-flavored cereal for breakfast, his heart pumps out of his chest to indicate the caffeine kicking in as Cow reads the list of ingredients from the cereal box.Nevermind that he's actually a vegetarian.

It's revealed this is because her cause of death was a heart attack. When this happens in public, she physically tries shoving it back in to keep her cover as a normal human from being blown. Zombie Land Saga has an interesting twist on this trope with Lily, a zombie whose heart is exposed and balloons out of her chest when she is nervous or terrified.Sanji does this frequently whenever he sees a beautiful woman.This happens once to Momoko in an episode of Powerpuff Girls Z.One could argue that since he's a robot, his internal organs are placed a little differently.
