We know what you're wondering...what the hell is a ninja is doing on stage at the Y Design Conference? Ask a Ninja creators Douglas Sarine (dressed and in character as Ninja) and Kent Nichols began their presentation by answering that very question.

Ninja: What are we doing at a design conference?

Nichols: Well, you're wearing all black. Don't you fit in?

But fitting in became irrelevant once they showed the latest episode of their web show, which amazingly featured an interview with Blades of Glory stars Will Ferrell and Jon Heder. Ninja was upset they didn't kill anyone with their "blades" of glory. This is a show that started in their tiny West Hollywood apartments.

Nichols and Sarine first started down this dark path with an animated screenplay about ninjas in Orange County, which has evolved into one of the most popular shows in history--Ask a Ninja has been viewed over 20 million times. With Ninja as moderator, they engaged in a discussion about creating with accessible tools, having an audience that pushes back, and developing a brand, but mostly they were just really, really funny.

Of all the audience questions, Sagmeister asked the best one. "I have a question about light," he said in that sexy Austrian purr. "Is it a particle or is it a physical state?"

Ninja: You live in the light you create.

Nichols: The light you take is equal to the light you make.

Sagmeister laughed and seemed to be pleased with the answer.
