Bare Knuckle: Bar Fightin' Guide

From Introduction:

Oh, man! We're gonna have some fun now! Why? Lemme’ tell you why. This guide is designed to be a fun, diversionary adventure booster and helpful addition to the D&D - 3rd Edition game rules. In the Dungeon Master's Guide and Player's Handbook, the basic combat system allows the Dungeon Master to run a variety of typical combat situations. I hate typical! In this manual, the focus is on rowdy, destructive, entertaining, and (mostly) non-fatal brawls. The kind that spring up in the bars, taverns, and inns whenever dwarves or barbarians aren't being watched closely!
