Humor is about culture. If someone is not from your country, they might not get your jokes, but they get local humor. She Who Must Be Obeyed bursts out laughing when watching interviews of Thais.
I have one joke in Thai that has people laughing out loud. I have brought the house down at lectures and weddings, but westerners will never get it.
"Excuse me if my tones when I speak Thai are flat, but my wife comes from Suphanburi."
It sounds better in Thai.
