Dil can burp the 50 states. (edit) The sign in front of the heart exhibit, indicating it's closed, reads: "Please excuse us while we mend our broken heart." (edit) Earlier in the episode, Justin's voice is similar to Nick Dean, from The Adventures of Jimmy Neutron: Boy Genius. Later, Justin's voice sounds more like Snap from ChalkZone. Those three characters are all played by Candi Milo. (edit) Justin's name is never mentioned, except in the credits. (edit) Grandpa Lou mentions the incident from the Rugrats episode, "Naked Tommy." (edit)

Chuckie: Now I know why it was called the spleen screeeeaaaammmm! (edit) Phil: (Receives the liver key chain) Cool. Now I have a liver inside and out. Love the key chain.
Lil: Good. But you still need a key. (edit) Lil: We're catching up fast.
Phil: Yeah, but it'd be nice if we could at least stop and smell the mucus. (edit) Chuckie: (About his key chain) I'm giving this one to Kimi, 'cause she's a good kid... ney. Get it? Kid-ney? (The others stare at him blankly) Okay, off to the thigh. (edit) Mr. Beaker: And that's what makes the appendix one of the most impressive, yet utterly useless organs. (edit)

In the scene where Tommy is telling his grandpa that he's embarrassing him, Grampa Louis gets mad and says that because he's old and has a hearing aid. then he proceeds to pull up his underwear, but it sounded if he was wearing a diaper. (edit) In the scene where Grandpa Lou looks at the giant heart, where Tommy and the other kids are trapped, you see that the door that leads inside the heart is open. But a few seconds later, when you see Tommy inside, you see the door is blocked. (edit) In one scene, Phil's hair turns a dark reddish color. Then in the next scene it's back to normal. (edit)

Episode Title: The Old & the Restless
This is a reference to the long-running soap opera, The Young and the Restless. (edit)
