Me: “Hello, miss, can I help you?”

Patron: “Yeah, I’ve been searching these shelves for about ten minutes and I can’t find any books on this one guy.”

Me: “Who are you looking for books on?”

Patron: “Oh, I think he’s quite famous! Wait, I know his name.”

Me: “Well, what did he do?”

Patron: “Something to do with the army…”

(The patron pauses for a bit before realizing.)

Patron: “Oh! Darth Vader!”
