Go visit the longest named train station in the world. The town has become famous because of its very long name. It has the longest railway station name in the United Kingdom, and now the longest single word domain name in the world.
Drop into the tourist information office in Llanfairpwllgwyngyllgogerychwyrndrobwll-llantysiliogogogoch, ask the staff nicely, and they will happily pronounce the name of the town for you.
They get asked to do this many times a day, every day, so remember to be polite.
