These Canadian comedians mean to make you laugh but they are also throwing punchlines at a wall of prejudice.
They all have mental health problems, and all want to rise above them through laughter.
David Granirer, who takes medication for depression himself, has been teaching them a course called Stand Up For Mental Health since 2004.
He now runs classes in Vancouver, Toronto and Ottawa, as well as performing himself.
Graduates include Alex Winstanley, 23, who mines for jokes the schizophrenia with which he was diagnosed three years ago.
The two men talked to the BBC World Service about passing the microphone to the mentally ill.
A life of material
"The more screwed-up and dysfunctional you are, the better your act is going to be" is what David tells his students.
"Your life is your act."
Alex, who believes he will probably never stop "hearing voices" but says he has learnt how to deal with it, feels "more alive on stage than in real life".
"I'd find that after a show, I'd feel so exhilarated I actually wouldn't hear voices for a few days or, if I did, they would be positive," he adds.
David tells of one woman with schizophrenia who came into class one day wearing a striped blouse.
"She said 'The voices haven't let me wear stripes for eight years but now that I'm doing comedy, I'm not so afraid of the voices, so I'm wearing stripes'."
Succeed in stand-up "and you feel like you can do anything", says the teacher.
ALEX'S FAVOURITE JOKE
Having schizophrenia, I spend a lot of time being jealous of so-called normal people my age.
I've always wanted to have a dead-end job and a divorce.
Sometimes I imagine a so-called normal person being jealous of me: "Alex, you have, like, a natural gift for, like, hallucinating. I have to drop two hits of acid to get anywhere close. And I'm so, like, lonely, I wish I had voices to keep me company."
