Lyrics

All action is reaction
Expansion
Contraction
Man the manipulator

Underwater
Does it matter
Antimatter
Nuclear reactor
Boom boom boom boom

I guess everything’s irrelative

I’m a janitor
Oh my genitals
I’m a janitor
Oh my genitals
Oh my genitals
I’m a janitor

All action is reaction
Expansion
Contraction
Man the manipulator

Underwater
Does it matter
Antimatter
Nuclear reactor
Boom boom boom boom

I guess everything’s irrelative

I’m a janitor
Oh my genitals
I’m a janitor
Oh my genitals
Oh my genitals
I’m a janitor

It has been said that the lyrics of “Janitor” were derived from a real-life conversation between Sue “Su Tissue” McLane and friend Brian Smith. According to Smith, the two were conversing in a loud room when they first met:
She asked me what I did for a living. I said “I’m a janitor,” and she thought I said “Oh my genitals.” [Richard “Frankie Ennui” Whitney] overheard this and wrote the song.
According to Richard Whitney, this story is somewhat backwards; the music and all of the lyrics apart from “Oh, my genitals! I’m a janitor!” were already written when Sue McLane added them herself:

I’m a janitor
Oh my genitals
I’m a janitor
Oh my genitals
Oh my genitals
I’m a janitor
