Firewood?

A curious fellow died one day and found himself waiting in a long long line for judgment. As he stood there he noticed that some souls were allowed to march right through the gates of heaven - others, though, were led over to Satan who threw them into a burning fire pit.

Every so often, instead of hurling a poor soul into the fire, Satan would toss the soul to one side in a small pile.

After watching Satan do this several times, the fellow's curiosity got the better of him. So he strolled over and tapped Satan on the shoulder.

"Excuse me, Prince of Darkness," he said. "I'm waiting in line for judgment, but I couldn't help wondering why are you tossing those souls aside instead of flinging them into the fires of hell with the others?"

"Ah," Satan said with a grin. "Those are from Seattle ... they're too wet to burn."
