Harper's spontaneously improvised "how to clean the fishbowl" song

Mimi: Those fishtanks are disgusting, and those fish are gonna die. SOMEone needs to clean those tanks!

Aubree: If by someone, you mean ME, you've got another thing comin'. When's the last time YOU changed the fishtank?

Mimi: I don't DO fish pets.

Harper: I KNOW HOW TO DO IT, MIMI! Want me to teach you?

Mimi: Why YES, Harper!

Little did I know what musical gift was about to be bestowed up on me and now YOU!
