Tim: Let me ask you guys a question that I'm sure most of us want to know. Do your mothers worry about you being in outer space? Ken?
Ken Bowersox: No, my mom never has a problem with me orbiting around the Earth. She only gets nervous when I fly in those small airplanes.
Tim: [nervous chuckle] Jill, I'm sure he's just kidding around. So, Al, guess what I have in common with all these astronauts.
Al: You've all had a fire lit under your butt and shot into space?
Tim: Well, that and Ph.D. If you remember, a couple of months ago, I got a Ph.D. All the astronauts also have Ph.Ds.
Ken Bowersox: Actually, Tim, that's not true. Everyone has one but me.
Tim: Well, isn't that a shame, Ken? Do you guys razz him for not having a doctorate?
Cady Coleman: No, we don't, Tim.
Tim: Why not?
Cady Coleman: 'Cause he's the commander.
