Saw this displayed on the side of a local pub and couldn't resist. Below is some info that I found on the
UFC.

The Ultimate Fighting Championship (UFC) is an American mixed martial arts (MMA) promotion company and the
largest in the world. It hosts most of the top-ranked fighters and produces numerous events worldwide. The
UFC has seven weight-divisions and enforces the Unified Rules of Mixed Martial Arts. Inspired by vale
tudo tournaments in Brazil,[9] the UFC and the sport of MMA have roots in the ancient Olympic combat sport
of Pankration in 648 BC.[10] In 1993, the UFC held its first competition in Denver, Colorado. Showcasing
fighters of different disciplines—including boxing, Brazilian Jiu-Jitsu, wrestling, Muay Thai, karate and
other styles—the UFC sought to identify the most effective martial art in a real fight. ~ Wikipedia
