Jimmy Kimmel created a series on his show involving celebrities reading mean tweets to make fun of the criticisms they get as public figures.
However, the segment isn't very funny when kids re-enact the skit with real tweets.
The Canadian Safe School Network had a group of children read aloud the tweets they received online to shed light to the effects of cyber bullying.
At first, the tweets seem funny. Then, the video takes a dark turn.
