Social media isn't just about fighting over politics, it's also a place where you can go to sling mud at your favorite celebrities. Every so often we take a moment to shine a light on the many evils of Twitter by letting famous people read some of the poisonous comments about them. We've done it again in an all-new edition of #MeanTweets starring Brian Cox, Chris Rock, Matthew Broderick, Kevin Bacon, Idris Elba, Dan Levy, Kirsten Dunst, Andrew Garfield, Jason Momoa, George Clooney, Salma Hayek, Jon Stewart, Halle Berry and Larry David.
