Making Up Lyrics

We were playing an audiobook for the kids. It's a story for kids about a brother and sister that travel through time and visit historical events. At the end of the CD, there's a song sung by the brother and sister. The song is titled "What would I do without you?". Near the end of the song, they start singing things like "I'm the sock, you're the foot. I'm the pancake, you're the syrup". The kids started making up their own version of the lyrics. Things like "I'm the ocean, you're the waves". Little Man came up with the best new lyrics - "You're the boogers, I'm the nose".
