Phineas: My baby's got her own way of talking,
Whenever she says something sweet.
And she knows it's my world she's a-rockin',
Though my vocabulary's [bad word] 
I know it may sound confusing,
Ferbettes: Ooh!
Phineas: Sometimes I wish she'd give it to me straight!
But I never feel like I'm losing,
Candace/Ferbettes: Losing!
