Once I was on a specialized two person team in Afghanistan. They needed to swap out my teammate the incoming guy had spent almost his entire life on Guam. He had no concept of sarcasm at all. Before coming in country to join me the unit provided him a sensitivity brief because I was known to be exceedingly sarcastic and to not be offended by it. He adapted to my conversational style super fast and I was actually exceedingly sarcastic. He found it hilarious all the time.

Any attempt at humor can be offensive. Know your audience. It does not matter what you intend, but how they perceive it. Just relax and be a team player.

I also worked with a guy who memorized all the lame dad jokes he could find and many were really funny.
