I remember when I was a kid and we started learning foreign languages in school. My class got divided into two halves, ones that study English and other that study German. Few month later I was walking down the street with my classmate and he went like:

• Oh, so you're studying English, huh? What does DUHR mean?

• What?

• DUHRR

• Oh, you mean door? It's spelled do-o.

• Bro, there's an R in there and two O's. DUHR. Even I know that, and I'm not even the one studying English. If door was do-o, then would you spell TOH DOH as "to do"?

Little did the bro know... I hope he at least got German well enough, AFAIK there's little bullshit like that
