[Chorus: Stewie Griffin & (Brian Griffin)]
I want a little brother (Mmm)
On second thought (Mmm)
I think I'd kill him dead (Mmm)

[Outro: Stewie Griffin & (Brian Griffin)]
Can we just cut Brian's mic? (Mmm)
His humming sounds like my table's ready at Chili's (Mmm)

[Performed by Seth MacFarlane as Stewie and Brian Griffin]
