It's long been known that "bad boys" make good girls go ga-ga. But what's the appeal anyway? Justin Bobby is the quintessential "bad boy" on The Hills. I can't find any redeeming qualities in him, except for the fact that he's a great source of amusement— from a distance. Can boyfriend be any more self-involved and publicly piggish? Yes, he can. And watch out ladies, his type is everywhere.
