During the trip-to-Comicon talk Howard said he somehow equates being able to sleep (on a plane) as a sign of low intelligence. I think quickly after the old chestnut of "Oranjooth boff..." he mentioned it. It isn't too hard to do the Howard-math though. Work hard, even on the plane, reach your destination, stare at the wall for an hour or two, then right to bed - at 8:45pm. That's much smarter than catching a rest and being effective later. All this running around, with the flying and the travel...fehh.
