- You refer to a local major highway or expressway using the definite particle and it's numerical identifier, but not it's alphabetical designation, i.e., "THE 5", "THE 167." To a Washingtonian, this screams "I'M A CALIFORNIAN!!!" Whatever you're trying to sell, forget it.
- The name of the town in which the Western Washington Fair is held is NOT pronounced "Poo-Wallop." Sheesh.
- The local mollusk with a long "siphon" that causes prudish little old ladies who see it to giggle nervously is pronounced "gooey-duck", with a hard "gee", NOT like it is spelled. Say "Geo-duck", with a soft "gee", and we'll all laugh in your face.
Then again, I also recall an ad from a station in Detroit that used the same theme, in which a taling head pronounced "Gratiot Avenue" ("Grash-ut") as "Grat-ee-oh", and "Escanaba" as "Escabana." (The latter only really jars Yoopers and we trolls who wished we had been born Yoopers...)
