The biggest disabilities are when you sabotage yourself mentally, those personal demons that get on your shoulder and you can't shake 'em.

I do a lot of conferences, and I did a campaign with the Cerebral Palsy Foundation called "Just Say Hi." They get celebrities to record little messages about how you start a conversation with someone who has a disability, which is to "Just say hi."

I didn't feel like I was putting anything good into the world, even though it was funny. I wanted to do something more positive that would have an impact. So even when I'm doing naked push-ups or whatever, it's astounding to see how people respond to it.

I feel that religion can be used as a tool to guide your life and help you connect with other people.

I feel a lot of personal responsibility to undo the negative stereotypes. I know that it's not coming from a bad place. It's coming from an ignorant place. I can sort of be an ambassador in a subtle way to say, "This is what I am: a comedian, a show host, a writer." It will still always be part of the conversation and people will want to focus on it because there is a culture that is so embedded that if you have a disability, you're someone to be either admired just for living, or be pitied for having to struggle.

My experiences of traveling abroad and going to Italy with my father, having to break down a gigantic electric chair to get on trains. You've got three minutes. You go to Pompeii and there are shockingly few accessible hotels in a city that was covered in volcanic ash.

There was an agent who wanted to book me for Glee. He lied and said I could sing. He was like, "If you need a guy in a wheelchair who has a great voice, I've got your guy!" I was like, "What are you talking about?" .
