I think comedy has evolved like every art form, and people probably do less standing around and telling jokes, and more things that have to do with reality.
In zombie horror, the juxtaposition of the calm world of the living and the menace of the undead inspires terror. In zombie comedy, like 'Pride and Prejudice and Zombies,' it is played for laughs.
On 'Adam Ruins Everything' we do the broadest sketch comedy possible. We do stuff where you can see it immediately and know it's a joke - characters in big silly costumes; here's Uncle Sam and he's twiddling his fingers saying, 'Oh, I'm naughty.'
Growing up as a comedian the most influential person on me was Jon Stewart. He showed that comedy could have a real tangible effect on the world. He showed that comedy could move the needle of society and that a comic can do real things and make a real contribution.
One of my favorite things about sketch comedy is doing parodies and music videos.
