How fast can I get mutalisks as Zerg and what's the build order to get there?
Here's a very detailed build whipped up that gets 5 Mutalisks @ 6:36. It's possible there is a slightly faster build for 5 muta, but this will do. As said by other users, I would not recommend this build as it leaves you open to attack for over 6 minutes. If your opponents scouts you once, you will probably die... Might be viable on certain team maps though.
EDIT: I removed the previous 4 Muta build I had because, even though it's faster, anything less than 5 Mutas is worthless. 5 Mutas is the magic number needed to one shot your opponent's workers. If you only have 3 or 4 Mutas you will not be able to adequately harass your opponent, so it's better to wait for 5.

In general, you should always get metabolic boost(speed zerglings) before going Lair tech. That said, here is a build (popularized by idra) that I would recommend using:
- 9 Overlord
- 14 Extractor (3 Drones asap)
- 14 Spawning Pool
- 15 Overlord
- 16 Queen
- (@100 ) Metabolic Boost (Remove 2 drones from gas) *
- 18 2 pairs of Zerglings
- 20 Hatchery (3 drones on gas)
- (@100% Queen) Queen
- 24 Overlord
- (@100 ) Lair, Gas
- (@100% Lair) Spire
- (@100 ) Overseer
This build sets you up with a good economy and allows for any necessary defense or early pressure.
So there is an 8 Minute Mutalisk strategy which does leave you sort of capable of defending yourself until your boys are in the air. There are rumors of a 6:30 Mutalisk strategy, but you're cutting everything from defense to drones.
Both of these builds are pretty bad; and I think its important to discuss why they are so very bad and why you should never do them.
Mutalisks are a fairly high tech unit. In addition to requiring heavy gas, they also require a Lair and a Spire, both of which are Gas heavy and have long build times (not to mention the Queen problem). Even if your opponent doesn't harass you in that time, the normal timing pushes tend to be around 6 minutes. This means that even if you do get your first couple Mutalisks in the air, chances are he's got a strong enough force to just roll you.
Strong Mutalisk builds (ie. not these) usually revolve around having 2 Bases. However, for earlier Mutalisks (6:30) you need to skip that second Hatchery. This means you won't have the production possible to bring about a strong Muta ball, or the resources possible to expand to get to that point.
Finally, you don't see Protoss looking for "Fastest Colossus Possible" builds, because a Colossus requires good Gateway support. Likewise, Mutalisk need strong ground support. The Mutalisk itself is design for hit and run tactics. If your opponent pushes out with a strong MMM or Gateway units, you're going to collapse, and your Muta won't be cost effective.
I realize my trying to dissuade you may seem a little odd since you didn't ask that, but rather how. However, I feel like this question is similar to asking: How can I stick a Fork in a light socket. If you know enough that it isn't dangerous for you, then you know enough to figure it out on your own.
