I may be confusing myself here. It's a passage I read ages ago, a guy is shown hell where people have six-foot long chopsticks and a table of endless food. They can't eat because they keep missing their mouths. The guy is then taken to heaven, where he asks "Do they get shorter sticks then?" the person showing him (maybe an angel?) says "Oh no, the sticks are the same length, it's just that the people here know that if you feed your neighbor, he will feed you also."
I think it was a Christian passage.
