When Grampa was posted overseas during World War II, he used to go to the pub. It was very popular, and lots of people went there to dance, sing, and drink. The Simpsons visited the pub during a trip to Ireland and learned that business had declined when Ireland became more modern and more people in Ireland started working. Homer and Grampa bought the pub after they got drunk with Tom. They renamed the bar "Simpson & Son's Pub." At first, business remained slow, but the pub became popular again after Homer and Grampa started allowing people to smoke inside. However, since this was against the law, Homer and Grampa were arrested and deported back to America. It's unknown what happened to the pub after that; it's possible that it was closed down because of the smoking violation.
