I hope that Elisha Cuthbert (star of "The Girl Next Door" and "24") gets to be really famous. Once she becomes a household name, maybe people will quit mispronouncing mine.
It's not Culbert, Culthbert, Culthberth, Cutberth, Cuthberth, Culbreth, Kubert, Q*bert, or any other number of butcherings I've heard over the years.
It's very simple. Eight letters, two syllables. And it's already spelled phonetically ie. it is pronounced exactly as it is written. Cuth-bert. There. See? I knew you could do it.
