Obama on SNL

Sen. Barack Obama (D-Ill.) performed in the opening skit on "Saturday Night Live" over the weekend. The skit featured a Halloween party hosted by Bill and Hillary Clinton (SNL's Darrell Hammond and Amy Poehler), at which Democratic presidential candidates arrived in costume.

Obama arrives wearing a Barack Obama mask. He removes it and explains, "I'm not going to change who I am just because it's Halloween."
