An Englishman, An Irishman and A Scotsman

"An Englishman, an Irishman and a Scotsman" is the opening line of a category of joke popular in Ireland and Great Britain. The nationalities involved may vary, though they are most usually restricted to those within the UK and the Republic of Ireland, and the number of people involved is usually three or sometimes four. In Ireland, the characters are sometimes called "Paddy Irishman (or a Corkman), Paddy Englishman, and Paddy Scotsman". The punchline is usually based around the Irishman's stupidity, the Scotsman's meanness (or frugality) or the Englishman's snobbishness. Sometimes, when the joke requires four people, a Welshman is brought into the joke.
