maybe:
"nicht ich!"
which means "not me".
This would probably more a question for my brother.....
As if! Why should
I suddenly be able to speak proper German? I'm Austrian too, remember?
I've been thinking about this question too, because we translate some material into German. But in some cases it's simply not possible... This strip is quite a tough one too...
What I would maybe use is "Du bist's" (It's you!) which is what I remember we were using as kids during the tagging game, right? Doesn't really fit the last picture though...
