Ladies, if your man doesn't know who Lando Calrissian is, shut it down! Star Wars is something that all men should have at least a working knowledge of. Incomplete (or nonexistent) knowledge of the Star Wars universe is an indicator of not only a complete denial of popular American culture but also of paranoid-schizophrenia.
One who doesn't know at least the fundamentals of Star Wars is completely missing out on a key part of Americana. This may be due to poor parenting, being too popular in school, or being home schooled and, ladies, I know that you would never seriously date or marry a "person" who experienced any of these conditions.
I suggest using the Star Wars as a personality litmus test. Just know that a "man" who has ignored the Star Wars universe is no man at all. Ladies you have some leeway, but men love a girl who appreciates how cool Boba Fett is.
Also, guys who wear baseball caps in situations where it is not called for are jerks, (e.g. a classroom setting, or other places that aren't outside) seriously fellas, buy a comb.
Oh, and guys who wear white-framed sunglasses inevitably have copious amounts of debt. Be forewarned.
