Where did the phrase never trust a man with two first names originate?

Answer 1

Sealy Booth on 'Bones'. 'Bones' premiered in 2005.

2XS, a Shadowrun novel by Nigel Findley (first published by the Penguin Group in February 1992) used the phrase as well (final line of chapter 21).

Not sure if it originated there, though. Joel Hodgson used the phrase, "Never trust a man with two first names, especially if one of them's a woman's" in an episode of Mystery Science Theater 3000 lampooning The Legend of Dinosaurs (Kyôryuu: Kaichô no densetsu). It is used during the opening banter between Joel and the "scientists". The episode aired on 28 May 1989, making it the oldest reference I can find.

I did a number of Google searches, restricting the time period and incrementally expanding it. The MST3K reference was the first that came up in a 2001 posting on some board, referencing the 1989 episode.

Answer 2

The phrase "never trust a man with two first names" is likely a humorous saying that plays on the idea that having two first names can make a person seem untrustworthy or hard to pin down. There is no specific origin or source for this phrase, but it is often used as a lighthearted joke about people with two first names.

Answer 3

Maybe it's a subconscious conflict in the mind, asking yourself; "who am I?" since childhood, he will especially realize this when he has an acquaintance with a name similar to either one of his names. I am curious if the myth applies to both sexes equally although I can't think of any off the top of my head I imagine there is a Stephanie Tiffany or a Catlin Stacey out there, it's 4 in the morning where I am, I'm tired and I want to go to bed.
