Hawaii Five-O/Trivia

Fake Nationality
- Wo Fat, played by Anglo-Egyptian-Sudanese-American Khigh Dheigh. Yes, really.
- In "Samurai", Mexican-born actor Ricardo Montalban played a Japanese mobster.
- Spock's dad played a Japanese saboteur in "To Hell With Babe Ruth." Oh dear.
Forgotten Theme Tune Lyrics: The show's distinctive theme music is entitled "You Can Count On Me", and Sammy Davis Jr. at one point actually recorded it:

If you get in trouble, bring it home to me
Whether I am near you, or across the sea.
I will think of something to do.
I'll be on the lookout for you.
And I'll find you -- you can count on me.

Missing Episode: "Bored She Hung Herself", a 1970 episode about a deadly yoga technique that bears more than a passing resemblance to Erotic Asphyxiation, has been banned since its original broadcast, allegedly because a viewer accidentally died while imitating the technique. The episode was never syndicated, and it's not included on the second season DVD box set.
The Other Darrin: Tim O'Kelly as Danno, Lew Ayres as The Governor and James Gregory as State Department official Jonathan Kaye (a recurring character on the series) in the pilot movie; Ayres later guested on the series (twice, in different roles), as did pilot cast members Andrew Duggan (four times!) and Leslie Nielsen. Kaye, meanwhile, was played by a total of six different actors.
Playing Against Type: Andy Griffith is a con artist in "I'm a Family Crook -- Don't Shoot!"
Trope Namer: For Book'Em Danno.
