The biggest challenge [making Pineapple Express] was that we had a comedy budget. We really got excited the more we got into the development of it about blowing stuff up and having shoot outs. That stuff costs money.

I did karate for a really long time, almost 10 years when I was younger.

I have become a giant fan of the testing process, especially with a comedy. I mean, they tell you what's funny. It's almost tailor-made for people who shoot the way we shoot, trying a million different options and versions of things. Because the audience doesn't laugh at a joke, we put in another joke. If they don't laugh at the next joke, we put in another joke. You just keep doing them and you can get the movie to the point where every joke is funny, if you have enough options in the can.

Good comedy doesn't have to be a comedy idea.

For me and my wife...the easiest part of my life is my marriage. Like if everything was as smooth and easy and fun as my relationship with my wife then I would have a much easier time getting through the day. We really get along and we like the same stuff.

Honestly, it's really hard improvising and it's really stressful and humiliating at times. You're taking really big swings that potentially are eating up a lot of people's time and resources at set in your attempt to discover something funny.
