John Larroquette was asked, during an interview, about the most interesting/surprising moment on the show. He responded that an actress who turns her back to the camera and then flashed him was supposed to be wearing short pants and full shirt but decided to wear significantly less as a joke. He was of course referring to the character Kitty played by a then lesser known Teri Hatcher.
The basis of this episode is the legal battle during the making of The Legend of the Lone Ranger (1981). Clayton Moore, the original TV Lone Ranger, was still making personal appearances as the character when filming began. The Wrather film company, who had purchased the rights to The Lone Ranger character, sued the actor to prevent him from wearing the iconic mask, saying an elderly man didn't represent the character the way he should. Moore switched to oversized sunglasses to replace the mask. He later won a countersuit, allowing him to appear in the original mask (most notably in Stan Freberg's classic Pizza Rolls commercial).
The title refers to the question a stranger would ask at the end of each week's The Lone Ranger TV show: "Who was that masked man?"
In what must be a case of cowboy karma, the actual Lone Ranger movie that spurred the producers to bar Moore from wearing the mask was a financial disaster for the them. when it laid cow patties at the box office.
