Am I missing an eyebrow?

Sometimes my brain writes a check that reality can't cash.

Isn't television glamourous?

I find that your basic Internet chat board is way too vitriolic for my taste.

It's sort of a mental attitude about critical thinking and curiosity. It's about mindset of looking at the world in a playful and curious and creative way.

Audiences of critical thinkers are my favorite kinds of audiences. There are jokes I tell in the show that don't get laughs unless I am in front of an audience of critical thinkers. Put me in front of a crowd of science teachers or astronauts! The guileless aren't our audience - it's the critical thinkers we love.
