Bluejay, I think the song you're talking about is "Unrequited to the Nth Degree." It is indeed a LW3 song, on his "Unrequited" album. A bunch of great songs, including "Rufus is a Tit Man," about his son.

Rufus is a tit man
Suckin' on his mama's gland
He's suckin' on the nipple
It's sweeter than the Ripple wine.

Great song
