Last night, President Barack Obama went on The Daily Show With Jon Stewart for a mostly serious discussion of this election season's issues and how these last four years have gone. But it started off with a little teasing from Jon on what many (including Obama himself) consider a subpar first debate performance. Jon showed the president two photos of his wife, Michelle Obama, after the debates — one in which she's smiling and another where she doesn't look happy — and asked him which debate each one was from. Obama was a good sport, responding with a chuckle and a "Cute. Cute, Jon." But Obama was clearly ready to get down to business, mentioning how his social successes have included repealing "Don't Ask, Don't Tell," which discriminated military personnel based on their sexuality. This got cheers from the Daily Show audience, filled last night with female military veterans. And on his job of preventing things that don't work, he added, "You want a president in the oval office who's going to say, 'No, we're not going to amend our Constitution for the first time to restrict rights for gay and lesbian couples.'" See what else Obama said on the late-night show now!
