Baby

Its a song Finn sings in a autotoned voice in the episode The Jiggler.

Lyrics
Baby, I know what need. You want your baby socks for your little baby feet. Baby I know what you crave, you want to poop in your pants all day long well baby behave.

Verse 2

Baby you looking so good, you looking like you want some baby food. Baby you looking so fine, you look like you might start crying. I got to tuck you in girl, and sing melodies about babies.
