Some of my favorites are actually songs, ones my mom would sing ( I am 56).
-You are my Sunshine. -Pop Goes the Weasel. -This Little Light of Mine. -Billy Goat, Billy Goat. -If you're happy and you Know it. Good memories of books, rhymes, and songs.

Another thing we liked was repeating lines from ads when using the product : "choosey Moms choose Jif", "7up-crisp and clean and no caffeine", heart healthy Cheerios, etc...
