A few years ago, some boys from my German course thought it would be funny to do Nazi salute as often as they could. Every time their names were called -during roll call, when the teacher asked them to read a passage- they answered with "Sieg Heil". None of the other course participants found that funny, but we let them be. They were only teenage boys, and teenage boys were not exactly famous for their sophisticated sense of humour. It was also understandable that "Nazi" or "Hitler" were the first words that first come to their mind when Germany was mentioned; we were still in a beginner class, after all. Our teacher, however, got very stiff, and the boys got a strict warning not to do that again. 
 A few days later, our branch of Goethe-Institut held a seminar for teachers. The main topic was on how to prevent the students from commiting these Nazi-related faux pas (apparently there were a lot of students in our branch who did this). As a result of this seminar, we were given a special education session about why it's a great taboo to do Nazi salute and such, as well as the consequences. The boys swore not to repeat their behaviour anywhere, not even as a joke. "Because some things could never meant as a joke," our teacher said. 
 Then, several years later, when I randomly surfed 9gag, I found the trailer of "Er ist wieder da." Some things could never meant as a joke, I could still hear my teacher said, but I laughed until my tummy ache. Hitler seeing his country being led by a woman! Hitler talking to an immigrant woman! Hitler trying to sign up for an e-mail address! The sheer ridiculousness of those ideas made it even funnier. 
 I still could hear my teacher when I caught a glimpse of its cleverly designed cover in my favourite book store, but her voice got fainter and fainter. I fully intended to approach this book as something that would make me laugh, and it did gave me quite a laugh. It's hard not to laugh at Hitler trying to make sense of how internet works! His delusional thinking that everything modern and noteworthy were invented by members of superior Aryan race (e.g. Wikipedia was named after the Wikinger/Vikings) was just too silly. The number of misunderstandings, whether it's on Hitler's side, the Volk, or both, were just over the roof. Knowledge about the Nazi and Hitler's personal life no doubt helped me to understand the jokes better, because I didn't have to flip to the translator's notes or search the Wikinger-pedia every 10 minutes. 
 (On the other hand, I was quite astonished at how much I know about Nazi and Hitler's personal life. Must be those hours spent randomly checking Wikipedia after watching Der Untergang and reading Every Man Dies Alone!) 
 In the end it was about the power of media and how this "Hitler" tried to comprehend and use it for his means. Whether he was successful or not, it was up to debate. Could we really take him seriously, if he appeared once again, even if he started his career as comedian? And even without his having to be inexplicably awaken from death, could we really followed his ideas seriously at all? I will let the readers personally decide.
