World Champion Craig Valentine suggests you check the reference points in your humor. Make sure your references can be understood by your audience. Avoid jargon that will only be understood by a small group or that is not well-known to the nationality you are speaking to. (e.g., If in England and you talk about "football" that had better be English football and not American football you are talking about).
Referring,
