Joel McHale, current host of The Soup and star of Community, got his start in a Seattle area sketch-comedy show called Almost Live!  One of his cast mates was a former Boeing engineer named Bill Nye, who went on to fame as Bill Nye the Science Guy and hosting an eponymous TV show.

In this clip from an early episode from Bill Nye, we see an early (nerdier?) version of Community’s Jeff Winger as he tries to explain how warm fluids rise.
