Be a Dude! was offered in PDF as a "joke item" additional incentive in the Kickstarter campaign for the card game Romans Go Home!. The instructions for the game are a bit tongue-in-cheek, but the game has been playtested, and is a functional minimalistic RPG. It is also (therefore) diceless, unless one wants to enforce the "Advanced Rules" that state that disputed assertions by the guy (the GM) should be resolved by the GM rolling a die, staring intently at it for a moment, then telling the dudes (the players) what to do. Certain snarky elements of the rules appear to be clear jabs at traditional RPG elements; however, the rules are perfectly usable as intended, for quick, filler (and perhaps drunken) roleplaying with brutal, arbitrary, and potentially hilarious results.
The designer drew loose inspiration from Hit a Dude.
