I assume you were going for "weisst du ihn," since wissen only becomes wisst in the plural, and in connection to knowing a fact, not a person. E.g. "Wisst ihr wo ich wohne?" - do you (plural) know where I live?
To answer your question, I've never been to Vienna, nor have I met any of Sacha Baron Cohen's fictional characters. I assume that's the Bruno to which you refer.....
