Yes, I know that having Hitler say "Piss Off" in the phone scene (which only occurs once - and early - in this parody) is HRP's thing. However, there are two reasons for it appearing here. One - it was intended as a shout-out/nod/tribute to HRP. The other is because, well, I couldn't think of anything else for him to say when I was making this. Don't worry, this will be a one-time thing.
