Brody enjoys doing a sort of "ignoramus humor," where he pretends not to have the information everyone knows full well that he has. You've seen it before. Someone starts a thread about someone and Brody chimes in with "So and so? Who is that? Oh, weren't they on this back in the 1980s?" or some such nonsense. Those are usually accompanied by a picture.
For example -
Say someone posts a thread about Phylicia Rashad. Brody will swoop in and say something like. "Who is Phylicia Rashad? I've never heard of her. Where did she come from? Oh wasn't she on some little sitcom in the 80s with that one comedian."
Then there comes the picture. Brody might say, "Phylicia enjoys ham on Easter. As does her sister, noted choreographer and actress Debbie Allen."
