Welsh Pronunciation

A couple were on holiday driving through Wales, when they come across a road sign for:-

Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch

They both tried to pronounce it, but their attempts soon turned into a heated argument.

They were still debating it when they pulled into a roadside cafe for a snack.

As they were paying the bill, the wife asks the waitress: "Excuse me, but could you tell me where we are? But say it slowly."

The waitress rolled her eyes somewhat, but leaned forward and said very slowly:
"Liiiiiittttttlllllleeeee Chhhhheeeffff."
