Well I've decided to pick a random 1980's Magnum P.I. Episode which is from Season 6 called "I Never Wanted to Go to France, Anyway" where Magnum is investigating a murder at a traveling carnival owned by an old friend of Higgins and unfortunately after Higgins had T.C. doing a stunt with helicopter ( And not to worry no one got hurt and T.C. is fine ) but someone who worked at the carnival was found murdered and Higgins asked Magnum to help him out with the investigation and while Magnum goes undercover at the carnival grounds he see a clown and believes that he's somehow responsible for the murders and carefully watches him ( But Spoiler alert the Clown was a red herring and it was the guy in the Jason Mask, But you'll have to watch the Episode on who the Clown is? ) And can find 1980's Magnum P.I. TV Series on DVD or Internet Streaming Services, Now on with the show.
