Oooh. Hee hee. I might ask him something "deep" such as his philosophy on life or what he thinks about whether there is a God or an afterlife or something. I would probably also wonder what his political views are, stuff like that. I'm a dork!
Well, besides what most people have mentioned (mainly the political views etc.) Why does he think having a beard makes him look good? *laughs* (I know others probably strongly disagree with me). Personally I would rather Robert looked a bit more like Edward, you know clean shaven and smart.
