What do you call someone who speaks three languages?
What do you call someone who speaks two languages?
What do you call someone who speaks one language?
I used to hear that joke, but the punchline was "American". When I moved to the UK, the punchline was "British". Now I hear it again for the French.
Interestingly, it's doubtful that this punchline would be "Dutch" or "German". There are many countries for which this simply wouldn't be meaningful, but it's nice to know that Americans aren't alone in this.
