I know a much longer word. That's nothing. Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. It's a small town in Wales. I'm part Welsh and used to live there and never visited the town but have a wooden spoon (um) with it written on. My mum can say it, she knows it off by heart. I can say bits of it, but it's really difficult and I have to look at the word.
P.S. Ignore the space, Mibba automatically did that.
