Well, I was curious how it is pronounced today, not what the classical pronounciation was. So I'm happy about the answers. :)

I try to avoid saying it, lest he show up in my house.

He's the king god of thunder (and sexing up mortals), not Beetlgeuse.
"It's so hard to be humble, knowing how great I am."
They differ a bit, considering how different dialects branched. Modern Greek is based on the Alexandrian dialect, so they use the most recent pronounciation, which has a distinctive -phs sound. In Classsical Greek it most certainly sounded as -eús.
As for how z (ζ pronounced zeta) sounds, it is one of the three compound consonants (the other two being ξ and ψ), so it's a combination of -ντ (d sounding dipthong) and s.
....I just went on a philology rant again. Need to stop doing that.

But given the 'sexing up mortals' bit, would you want to risk it?
Uniocular
He's a god.
I doubt I'd mind if he'd want to make with the fornication.
"It's so hard to be humble, knowing how great I am."
Rhymes with "Goose".

Start with Dyaeus Pitar, then it's easy, you just have to follow the path of Greek language's evolution from proto-Indo-European.

Tse-us.
Zoose. Like Goose or Moose, but with a "Z".
Brohirrim
>:( ...wait... By Iuppiter, you used the Latin spelling! That's so exciting.
Er...sorry about the classical thing. I just thought it would be a fun, useless little factoid.
I pronounce it "zoos", in any case.

Come to think of it, when I do say it, rather than use an euphemism, I say 'Zyoos', 'cos I'm just like that.

The thing I like best about Spanish: not having to worry about stuff like this.
Likes many underrated webcomics
I personally pronounce it as Zee-ust (similar to the name Jesus, except with an enlongated Zee sound)
In an anime, I'll be the Tsundere Dark Magical Girl who likes purple MY own profile is actually HERE!
I draw stuff.
Zê - us. It rhymes with Deus to me.

We should ask this guy for advice.
I had to look that up and listen to a pronunciation, hahaa. It probably would have sounded something similar to that, anyway. Maybe more of a "d" sound along with the "z", if that makes sense.
I should add a disclaimer that of course we don't know exactly how the classical words were pronounced...they were similar to modern Greek, but how much the two pronunciations differ is up for speculation. There's kind of a raging debate going on right now, bloody linguistics!
