Can anyone confirm he works in comedy?

I read somewhere that Ben Stiller has acted in comedies. That he's a funny guy. Someone who makes you laugh. At least in the movies. I must have watched other movies with Ben Stiller then I guess as I don't remember a single scene ever that had Ben Stiller in it that was funny. And I think over the years I've seen them all.

I have the same question about Owen Wilson.

Or is it only 'Muricans that appreciate their kind of non-humour?

Same question for Seth Rogen.

And Robin Williams (extremely awful, never funny, very overrated).

And Will Ferrell (who hires this guy?).

And Jack Black.

Oh, and Mike Myers (the king of not-funny).
