Um, Jim? We didn't want to tell you this, but we cloned you for travel purposes. We've nicknamed him Jamison, and managed to engineer the motion sickness out of him. He'll take care of your appearances when you have to fly.
Unfortunately, there were side effects in making him non-dramanine-able, and, well...look, ignore that really large bar tab he rang up with Bob Asprin and John Steakley, ok? We'll work on fixing that.
