- The line "Hey you! Get off of my cloud!" was improvised by Graue during recording as an homage to the Rolling Stones.
- Graue finds it "flattering" that stuff that he did as a quick job in 1993 / 1994 would end up becoming famous on a whole new platform.
- He once said "YOU GUYS ROCK", apparently referring to us. D'aww shucks. Marc, if you're reading this, we thank you too.
