Victoria Rules
We're pretty open with character sheets these days, though such has not always been the case; I once ran a character as a "Ranger" for an entire 1st-Ed. adventure where in fact he was a Thief-Cleric(Druid)...rest of the players never did catch on...
And more recently in my game someone brought in a Thief-Wizard and hid the Wizard side (this player is known for playing Thieves so if she'd tried to play it as a pure Wizard everyone would have known something was up); halfway through the adventure someone noticed her casting a spell, and the jig was up.
