It might surprise you to learn that there’s a Unicycle Football League. It should not surprise you to learn that it exists in Texas. The San Marco, TX-based league clearly (see: video) doesn’t play the most elegant (or passing-friendly) version of football, but it’s nevertheless taken seriously: As described by the league’s rulebook (which, according to the UFL site, is “constantly undergoing revision as our sport evolves”), light tackling is permitted, but any hits that are deemed excessive (e.g. spearing, lest you “Break your damn neck”) is punished by penalty and loss of down.
And of course it's in Texas.
