If you want to get serious, how about Featherstonehaugh and Pontefract, the latter when a surname. And then there's Tollmache-Tollmache, or more correctly: Leone Sextus Denys Oswolf Fraudatifilius Tollemache-Tollemache de Orellana Plantagenet Tollemache-Tollemache*.
To give you a clue, the two Tollmache-Tollmache at the end are not pronounced the same way....
*The longest name in British army records. Oh, and pronouncing the two in different ways separates the toffs from the hoi-polloi as toffs would know how to pronounce all these names. Featherstonehaugh is pronounced Fanshaw, and Pontefract is pronounced Pumfree, though when it is a place, it is pronounced exactly as it is spelled!
