Slash, Ozzy Osbourne, and other musicians teamed up for a new anti-bullying documentary called #NoJoke.

The documentary follows the story of British singer-songwriter Andrew Cole’s mission to write an anti-bullying song. Cole tells the story of how when he was a kid, he went to “about 20 schools,” where he was “always the weird guy or the newbie.” He would confront the bullies, saying, “What do you think, I’m a joke? Do I look like a joke to you?”

Because of his personal experience with bullying, Cole set out to write a song called “Joke.” However, in order to gain attention, he had to go as far as to pretend to be assaulted by the paparazzi.

Eventually, Cole was able to involve celebrities, such as actor Jeff Goldblum, Slash, Chad Smith of the Red Hot Chili Peppers, and more.
