They should have sensory deprivation boxing done in complete darkness with ear plugs. They would just bumble around for a couple minutes until they bump into a post and break their fist on it.
They still do blindfold matches in Prowrestling every now and then. Really is the dumbest gimmick. The wrestlers just fumble around the ring till somebody cheats.
They do every gimmick on the charts up there. Mixed Gender, Child Boxing, Kangaroo Boxing, Cockfight Royale, Monkey Matches and Blindfold matches. Most of the more animal focused ones they don't put on during the high tourist season to keep the protesters away. Chiang Mai is the place to go for all those things that Bangkok can't quite get away with doing anymore.
