I love the underdog, pretty much every time. (Sometimes this backfires on a long enough timescale; ask me about my favorite football team.)
Highbrow/lowbrow: if I can come up with a joke involving, say, Edith Hamilton and TGI Fridays, I will. And if you get why that might be funny, we might have a shot.
(Also, why do so many people misunderstand this question?)
