"Oh, that's competely different. Never mind."

Here in the UK, the longest name of  any place is the famous Welsh one, usually written as Lanfair PG:
Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. There are many longer, including one in New Zealand with 92 letters.

 

This week it was admitted officially that yet another long place name, of a lake near Worcester, Massachusetts, has been spelled wrongly on signs as Chargoggagoggmanchaoggagoggchaubunaguhgamaugg for some years.

 

It should be Chargoggagoggmanchauggagoggchaubunagungamaugg.

The locals call it Lake Webster.
