Mixed martial arts became popular in part because of freak-show fights like the one between 200-pound Keith Hackney and 600-pound Emmanuel Yarborough at UFC 3 in 1994.
The UFC has largely done away with such oddities, and now is characterized by high-stakes bouts of physical chess between opponents who are roughly the same size.
That does not mean the crazy old days of MMA are truly gone. Take, for example, an upcoming fight in Japan between a 12-year-old girl and a 24-year-old woman.
The pre-teen amateur, simply called Momo in promotional materials, is currently in the seventh grade and weighs just 86 pounds, according to WMMARankings.com.
Her opponent, Momoko Yamasaki, is a professional fighter with a 2-3 career record. According to Deep Jewels, which is promoting the fight, Yamasaki was bullied when she was in junior high school and then became a street fighter before finally making her way to MMA.
