Lost in translation?

Today I received a funny joke. In German (ok I know, but don't even go there). Forwarded it to a friend. Got an answer "who the hell are you?". OK, you need to know that this guy is not exactly IT friendly. Which in a way is funny, since he works in an IT company. Go figure.

I responded (in German) saying "I am somebody who speaks German". He in turn responded (now having figured out who I was and still am), including correcting my German. Turns out I had the right grammatics, and he again responded saying "ok, so my grammer sucks"...yes, it does indeed. Also in English :)...which btw happens to be his first language. Hurray, I am good!
