" Sometimes I feel like people aren't listening to me. I spend ninety minutes up here talking about the dangers of time travel, advising you to stay the hell away from time travel, and the first question I get is: 'Do you think time travel will be available commercially?' Then again, I spend every waking hour bent over quantum equations, so I guess I don't listen to me, either.
