Dull-fest.
They should introduce large amounts of alcohol, 5 pints before each match and then one pint a frame or the first 5 frames, and see how it goes after that. When one player was at the table the opponent would be permitted to spill their pint but only if once a frame; it would all then kick off. Likewise the opponent would be permitted to "look at their burd" but if they were caught doing this they would forfeit the frame. Incorrect claims of "are you looking at ma burd?!" would result in a free punch being offered.
