david boreanaz What's the first thing you think of?
What's the first thing that pops into your head when you hear the name David Boreanaz? This is it for me: image
David (as Booth) stands in his suit, in the middle of a street, the sky white behind him, flashing a charm smile.
(I don't think this is from any individual episode, just what my brain flashes me, probably because of all the refernces to his "charm" smile, so in essence I could say the first thing for me is words: charm smile)
