Well, we could have the dwarfs and half-orcs settle the matter in a drinking and ass whupping contest...
Round 1: Drinking - Dwarf and half-orc begin drinking.
Round 2: Drinking - Dwarf and half-orc begin singing, using just their Charisma penalties for the rolls. Judges cover their ears.
Round 3: Drinking - Half-Orc slides under the table a full flagon before the dwarf topples off his stool.
Drinking Victor: Dwarf by a narrow margin.
Round 1: Ass Whupping - Half-orc enters rage and begins swinging bench, dwarf starts exchanging 'friendly' blows with a fighter in a gut punchin' competition.
Round 2: Ass Whuppin - Dwarf and half-orc begin singing battle songs, using just their Charisma penalties for the rolls. Judges cover their ears.
Round 3: Bench breaks over the head of a gnome blacksmith, human pukes on dwarf after the third round of gut punchin'. Dwarf leaves to wash beard under the pump.
Ass Whuppin Victor: Half-orc by a narrow margin.
Looks like it's a tie folks, let's leave before they start singing again.
