And here's something about satire, Stefan Kuzmany in der Spiegel:

"The man has been penalized enough already. If you have to rely on support from Mathias Döpfner, head of the Springer Verlag publishing house, and Dieter Hallervorden, who leads a cabaret theater in Berlin, you're not in great company. If you become famous, if you make history, with a few repugnant lines of clumsy poetry and not with your significant television skills, you have lost control over the popular interpretation of your own work. If the high point of your fame consists of calling the Turkish president a goat fucker and triggering an affair of state, you are not to be envied.

But Jan Böhmermann, author of the deeply insulting lyrical attack on Turkish President Recep Tayyip Erdogan, has little to fear should he face trial for violating German laws prohibiting the insulting of foreign institutions and representatives. Even if he were convicted, the absurdity of a prison sentence seems highly unlikely. And he would likely be able to afford a fine, particularly given the possibility that Döpfner and Hallervorden would take up a collection to help him pay."

Yes, the satire is mediocre, but mediocre satire is rarely deeply insulting.

Instead of attacking Merkel Der Spiegel should have attacked Erdogan who clearly believes that most of the world is his playground and he himself is the assistant to God, if not more than that.
