Here's another one:

Actress Elaine Joyce in "Just Lucky, I Guess" was too old for the role of the murdered young prostitute. She was 26 in 1969, yet her character was supposed to be barely 18. When McGarrett revealed her age, hapless Sloane was taken aback, muttering, "She looked at least 25!" I agree! In fact, the actress was even older than 25!
