I keep clicking back to the opening line and it's relieve. I always rememeber this song and the line "don't have a nickel..." when I first heard I thought Scott was making a racial slur
I'm sure when it was written it was intended to be "believe" but who knows how many versions of a song there are in recording. Maybe Dean just yells across the room..."If you wanna fuck, you wanna fuck, why don't you ask her to relieve you instead of believe you." Eric does a clever rim-shot and everyone gets a good laugh...what was just a joke has just changed the word in the song. Chords change, the tempo changes, a word here or there out of place in a song never really surprise me. Also, if you look through and read through the lyrics on core, purple and tiny music there are several questionable entries.
