Why do European and American jokes always make fun of Ireland?

Government officials are all British.

Where did you read that, my big brother? Can you name an Englishman who is a senior official in the Irish government?

Answer the landlord:

Because Ireland is poor in history, Irish people have more personality. Coupled with being ruled by Britain, the British naturally like to laugh at the Irish. Later, the Irish immigrated to the United States to do some low-level jobs and were also discriminated against.

But this phenomenon should be less common now.
