"Why on earth would you want to sing karaoke so close to our due date? It's harder to get a deep breath and sustain the note when I've got cubs pressing up against my lungs."
"True ... but it's still fun, and I love your voice. And I'm perfectly willing to use my pregnancy as an excuse to do irrational things while I can."
"... Sounds good to me. Something by Weird Al?"
"If I could marry you all over again, I would."

Other possible songs include "Don't Go Breakin' My Heart" and "Before Me and You."
