This table anecdote by Daniel J. Davis is one of the greatest examples I've seen of player-characters being player-characters. I love this stuff. It's why I love roleplaying games: seeing other people be clever (and, occasionally, horrifying).

For more clever, horrifying acts, check out The Initiate, from Baen Books. It will be in bookstores February 4, and is available for pre-order right now!
