MMA fighters are just guys who used to fight in bars ... most of them have killed small animals in the past ... or they are taking out their frustration of not being able to rape furry woodland creatures by fighting. Plus they are all addicted to Flintstones Vitamins and Smurf Porn.
^ just trying to live up to Tommy's expectations of guys who don't like the MMA
edit - forgot to say anyone who gets down on the ground and wrestles another guy in spandex is obviously gaye!
