Noted MMA official Herb Dean, often called the "best referee in MMA" by
UFC president Dana White, appeared on Tuesday's edition of "Late Night
with Jimmy Fallon," and a video is now available of the segment.
The NBC late-night talk show featured Dean in a familiar role: referee.
However, this was no MMA contest. Instead, Dean was enlisted to oversee an "important" Ultimate Mustache Fighter matchup.
