Last night, I went to visit Monty Python's Spamalot musical in Cologne. I had no idea, what to expect from it, and I was quite sceptical concerning the german translation. I was very surprised by the job, the whole team has done. It was very funny, in typical Monty Python style, many unexpected gags, and very ludicrous. I actually believe, they got some gags in german, that weren't in the english version. At least, I wouldn't know, how to translate it, to make it funny 
I'm very interested in the english version, though. Humor is definitely best in the original language. Nonetheless, the musical is definitely worth seeing.
