I was diagnosed with attention deficit hyperactivity disorder (ADD/ADHD) and obsessive-compulsive disorder (OCD) as an adult, but I don't remember a time when I didn't have them. Back in the 1960s, when I was growing up, my symptoms didn't have a name, and you didn't go to the doctor to find out.

I'm always in a hotel room, and I spend a good portion of my day setting it up so it's comfortable for me. Whether that means making paths out of towels so I don't touch the carpet or removing the comforters or just not touching things. Even sitting on a plane with a bunch of other people - it's really hard for me.

I once called construction companies to bid on an addition to the school library so that there would suddenly be people outside, measuring the building. 'Who authorized this?' the principal would ask. The answer: 'Howie Mandel.'

I once missed an appointment because I left my house, I locked the door. And then I thought, like anybody else, you know, 'I don't think I locked the door.' I just kept going back to the door. And I couldn't stop myself from checking and checking.

The main reason I got into comedy was in the hope that I could make a few people laugh and feel better about life, and the fact that I do that is quite overwhelming, really.

I never really thought of comedy as a career. My goal was, when I moved to New York, I was going to write serious films.

I love 'Another Round.' It's Heben Nigatu and Tracy Clayton's podcast that's through BuzzFeed, and they're real funny and really themselves. And I like it because it's very funny, but it's outside the realm of comedians talking about comedy.

Veerey Ki Wedding' is a comedy of errors in more ways than one. It's one of those basic, perky comedies. We're not trying to give out a message or anything.
