I had to write a comedy set and film a show at the same time. And it's the second time I've been up on stage as a stand-up comedian with untested material. I was saying it out loud for the first time that night. It didn't go how I expected, but in the best possible way.

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."

The waiter just flashed me something that said, "Chew bubblegum." Every morning, when I was about to go to the Oprah competition, my friend used to say this line in a video game to me: "It's time to kick ass and chew bubble gum." There's a strict policy that you can't encourage anyone on a reality show, that would give them an edge.

When I was a kid, I thought I would be an action-movie hero. I was like, "They're gonna be able to CGI my legs by that point." And then I realized that it was probably better if I stayed a little closer to who I actually am rather than trying to be Bruce Willis.

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

I would love to get an international version of Riding Shotgun going, because that's what I've been angling at ever since I wanted to do a travel show in the first place.

Having a son with a disability helps makes Walter White a more sympathetic character. There's no story line that shows Walt Jr. going through the things that you go through as a teenager with a disability. It's always his relationship to other characters. That was my issue with it.
