Thank You Mask Man is an animated short film based upon a comedy routine by Lenny Bruce involving The Lone Ranger and Tonto.

After years of saving a small town, its population is angered that The Lone Ranger never stays long enough to receive gratitude for his deeds.

A townsperson, bewildered at this request, asks the Lone Ranger why he wants the horse and Tonto; he replies "To perform an unnatural act."

The short was made by San Francisco-based company Imagination, Inc. and directed by Jeff Hale, a former member of the National Film Board of Canada.

[2] The film was scheduled to premiere on the opening night of Costa-Gavras’ political thriller Z, as a supplement preceding the main feature, but was not shown.

[2] George Evelyn, a former animator for Colossal Pictures, was working as a programmer at a theater in Texas, and booked the short without viewing it first, because the rental catalog "made it sound interesting".

[2] A heavily edited version of the short made its network television debut on CBS-TV's reality-based late night show No Holds Barred in 1980.
