I have to admit: I have been known to be obsessively neat and like things arranged 'just so.'

I'm happy to be the guy on the subway that people stare at and they just can't quite place it. I don't really like my life intruded upon too much. In a way, it's kind of nice to not be all that well known.

I hate to admit this, but before we had a baby I was kind of weirded out by breastfeeding. It looked strange, and I was always like, 'Look away! Ignore it, ignore the boobs in the room, move along, nothing to see here!'

Comedy can be more difficult than drama. It requires more attention to timing. In the theater, you're always dependent on the audience for the energy, but in comedy the feedback you get is more important. You can judge by the quickness and the length of the laugh just where you stand with the audience.

Epsilon 15's tail, for example, has six 'spikes' in it, but they aren't arranged in a neat hexagonal ring. They're highly deviant. Because they're so off-kilter, only two of the spikes actually grasp the shell surface. It's probably not very exciting news to anyone who doesn't look at these things for a living, but what it shows us is that the viral world holds many unexpected secrets, and if we're going to unlock them, we need to see them first.

A fan once stopped me outside a theatre and gave me as a gift a signed photograph of Sir Laurence Olivier. It was strange, but nice, too.
