Halloween is tomorrow, so this week people in the news were trying on costumes and masks, deciding who they want to be. In sports, the St. Louis Cardinals were the ultimate Cinderella, going from 10.5 games behind in late August to World Series champs. In the GOP race, Rick Perry couldn't make up his mind. At first he decided to go retro, donning a Steve Forbes-inspired look as Flat Tax Man. But I guess that wasn't scary enough, so he switched to a more modern -- and much creepier -- mask: Birther Guy. Meanwhile, the Oakland police department apparently has decided to come as Richard Daley's 1968 Chicago police force, with injured Iraq war vet Scott Olsen left looking like the civil rights protesters bloodied on Selma's Edmund Pettus Bridge. Lastly, what's the over/under on how many "Sodomized Gaddafi" outfits we'll see tomorrow night? Boo!
