As established in this question, "Rock of Ages" by Def Leppard starts with
"Gunter, Glieben, Glauchen, Globen"
because of an in-joke by the band and their producer, Mutt Lange.
But why does "Pretty Fly (For a White Guy)" by The Offspring start with that saame line? It even seems to be a sample.
Please note that I'm looking for sourced answers, not just opinion. It's obviously a reference to Def Leppard, but why? Are they big fans, or was it a suggestion by an engineer that they liked enough to use?
