In light of the Denver Broncos' Super Bowl 50 win, let's take a look back at our favorite Broncos cheerleader: the late Robin Williams.

At a 1979 game between the Broncos and the New England Patriots, Williams appeared in the cheerleading lineup, reprising his role of Mork from the Colorado-based sitcom Mork and Mindy.

He took the field alongside the Denver Broncos' cheerleading squad, the Pony Express, dressed in the team's glittering white ensemble. His appearance was later a plot point on an episode of Mork and Mindy.

In the lead up to Super Bowl 50, Williams' daughter Zelda shared the memory on Instagram.
