Was Robin Williams really a Denver Broncos Cheerleader?

So how did it happen? Well he was Mork from Ork ya know.

Robin Williams was an alien from the Planet Ork on "Mork and Mindy" which was filmed and based in Boulder, Colo.

On Sunday, November 11, 1979, Mork was a real member of the Denver Broncos Cheerleader "Pony Express" during a live game at the old Mile High Stadium in front of 74,000 screaming fans.

He dressed the part too, white knee-high cowboy boots, sequined mini skirt and gloves and a cute top that showed his hairy belly. That's dedication.

And for the record, The Denver Broncos beat the New England Patriots that day, 45-10.
