People can be mean and say some pretty hurtful things on social media. Celebs seem to be the target of choice for these Twitter trolls but most are so busy that they probably never see the hateful messages...that is, until Jimmy Kimmel forces them to read them! This is the 6th installment in the 'Mean Tweets' series and it's a riot!

Check out Tom Hanks, Joseph Gordon Levitt, Jon Hamm, Jennifer Gardner and Rob Lowe reading mean tweets about themselves!

Warning: Contains some use of profanity!
