President Barack Obama stopped by Jimmy Kimmel Live! on Thursday night and was kind enough to subject himself to a round of "Mean Tweets," courtesy of the show. Not only is it pretty special to hear Obama's very official presidential voice reading the cruelty of the Internet aloud, but he couldn't help but laugh and insert a few sassy comebacks along the way. The best part might be when he calls one tweeter's "LOL" redundant. Watch the hilarious video above, and then to keep the laughs going, watch all the previous editions of "Mean Tweets." [1]
