This is a song about Buford's pet fish, Biff, who was lost during the episode Voyage to the Bottom of Buford. The song has the same tune like the song "Without You". It samples "A Moment Like This" by Kelly Clarkson.
When I'm soaking in my bath
I dump you in the tub
There's no need to say another word,
You had me at "Glub"
Your bowl became my world,
So my world is empty now
All my love's caught in your filter
It needs to get to you somehow
They say that there's plenty of fish in the sea
but you're the only one for me.
Without you, I'm a fish out of water,
I'm hooked, please throw a line to me.
