The most important thing is to have the conversation, and let people who do make mistakes feel comfortable enough to continue the conversation.

I think that's where it comes into play, when you are just looking at a document or whatever and you see the word "disability." Does that automatically trigger something in you that denies someone their personhood?

I haven't found anything that I've wanted to say that I couldn't do through either the Internet or the reality shows that I've done.

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 have one of the worst voices in the history of recorded time.

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?" .

When I read the script [of Glee], the whole premise was that all the high school kids were being cruel to this kid in the wheelchair, and then the quarterback comes along and has a heart of gold and takes him out of a Porta Potty. That's too often what I see in media, that the characters with disabilities are there to make other people seem like heroes for treating the character with a disability with respect. Those are the kinds of roles that are out there.
