Poll: How do you pronounce the letter "z"?

[Mechanical Cat Fish]

It varies depending on my mood. I still say Dragonball Zee even though in England we generally say zed, and it was pronounced zed in the original Japanese, because that's just how I'm used to hearing it.

English: Zed
German: Zett

Zee.

How about the number 0?

I've heard Eddie Izzard and other europeans say "not" instead of "zero" Is that common?

"five, four, three, two, one, not, then what?" (on the B.C. A.D. changover)

I believe they pronounce it "naught"

What's the difference? Other than a better score in scrabble.
