The Weekly Grind: Anthony Johnson visits the dentist, Fabricio Werdum trolls Fedor and more

The life of a professional fighter isn't all glitz and glamour. As if getting punched, kicked, kneed, choked and twisted into a pretzel on a regular basis isn't enough, fighters attract a general wackiness that makes their lives, well, interesting. To commemorate these day-to-day hardships, slip-ups, pranks, and more, we bring you "The Weekly Grind." Enjoy.
I have decided to retire young.
Thanks for the cheese.Catch ya's later.
