Jimmy Kimmel's "Mean Tweets" has become something of a late-night institution. Typically, the host gathers a bunch of celebrities. He gives them a tweet someone wrote about them. The celebrity reads it aloud. It's all very fun. On Thursday night, President Obama decided to join in for a special edition of "Mean Tweets." Our Commander in Chief, as we know, has a pretty good sense of humor. So, he takes the social-media jabs pretty well. Watch as Obama navigates blame for things like the rising price of Coors Light. It's oddly patriotic.
