You’ve forced me to break out this old joke.

A Greek sailor is in port at New York City, and, like all good military men, decides to spend his time in a local bar, drinking. He sees a pretty girl, and says to the bartender that he’d like to buy her a drink. The bartender shakes his head, and says, “I don’t know about that. She’s a lesbian.”

At this point, the sailor rushes over to the confused girl, grabs her arm excitedly, and says in Greek, “No way! I’m from Lesbos too! I’m from Mytilene! You?”
