We [with Judd Apatow] started talking about ideas and he said, 'Well, I'm going to do this movie Knocked Up with Seth [Rogen], but after that you guys should do a movie together.' I read it and thought that it was very funny.

We originally actually wrote Franco's part [in the Pineapple Express] for me and the part I ultimately played just for someone else in general. Then when we got Franco involved we thought it was a good idea to switch the roles. I think it worked really well.

The great thing about reading for Quentin [Tarantino] is you're not reading for him, he's reading with you. So he sits right next to you.

After every single take, I laugh. It's my own awkwardness and discomfort about being an actor.

We don't have any changes in the movie [Pineapple Express] and so picking the right outfit was fairly important. So I wasn't a fan of the Guatemalan pants, but I was convinced that I should wear that. Then the T-shirt is a special creation by David Gordon Green. It's a kitten sitting in a shark's mouth, but he's happy about it.

For me to act natural and real but also try to be funny while doing that is hard.

I was in high school when Will Ferrell was first on 'Saturday Night Live', and I remember thinking, 'Man, that guy is the funniest guy ever.'
