Created by the same team that brought you Airplane! and Kentucky Fried Movie, Police Squad was a brilliant series that was unfairly cancelled.
The Premise was simple, Police Squad was a straight laced 70s crime show (heavily swiping from Quinn Martin shows) full of sight gags and jokes delivered with a deadpan nature. Leading the team was Leslie Nielsen as Frank Drebin, a straight laced no nonense kind of cop who is sometimes a sgt and later a lt detective, they kept intentionally changing that.
ABC cancelled the series because "the viewer had to pay attention" which means that ABC thought we were all morons, I was eleven and had no trouble keeping up. Police Squad! was a never miss program in my house.
After it's cancellation of course, the series was eventually brought to feature films as "the Naked Gun" making Nielsen a comedy star in the process. As much as I like those, I kind of miss when Frank Drebin wasn't a buffoon who seemed in on the joke. (In general I wish no one had ever told Leslie Nielsen he was funny) One of the best things about Police Squad was it's hard boiled tone.
