There’s an old joke that goes something like this:
A Chinese guy and a Jewish guy are arguing about whose nation is older. The Chinese guy claims that his nation has been around for two thousand years. The Jew says, “Well, we’ve been around for 3 thousand years”. The Chinese guy says, “That’s impossible! What did you guys eat for 1 thousand years?”
It’s not very funny, but it fits the topic of conversation (one of them at least).
