Don Pettit from low earth orbit:

The fatalist in me accepts the inevitable Zero-G result of landing jelly side “down,” so I decided to make sure the probability would always be 100%. Realizing that the bread is merely a vehicle for conveying peanut butter and honey, I decided to spread it on both sides. In weightlessness, it’s easy to balance your slice on its edge so that it can be parked on the galley table without any fuss.
