Friday and Gannon......

A few trivial facts about the famous duo...

Jack Webb would pay $25 to any L.A. police officer who submitted a story that was used for an episode of the TV show Dragnet.

Through all 100 episodes of the series, Friday is only seen wearing something other than his regular suit four times: three times for undercover work and once for a scene in his apartment.

Friday and Gannon used a 1967 Ford Fairlane 4dr. sedan as their squad car.

Gannon and Friday's car was known as unit 1K80

Bill Gannon was married and stated he had four children, while Joe Friday was a confirmed bachelor

When Jack Webb revived the show in 1966, it was in response to the growing tide of teen-age drug use, especially LSD.

For the sake of continuity, Friday and Gannon always wore the same outfits in every episode. According to Harry Morgan, he and Jack Webb decided to switch coats for one scene to see if anyone noticed. Because only Morgan was in the scene, no one on the set realized it until the scene had been shot. In the next scene, Morgan has on the correct coat. This is the only incident of faulty continuity in the series' run
