OK its not the NATO one - but if you wanted to really confuse people you could use the following that someone sent me as a joke once:-
Aye, Bee, Cue, Double-u, Ell, Four, Gibe, Hour, Iambic, Jay, Knee
Lye, Mnemonic, Nine, One, Psedonym, Quay, Repeat, Six, Tsar,
Urn, Veldt, Write, Xenon, You, Zero
PS I also concur - its Mike not Mama

As you can see, there actually is not much standardization of phonetic alphabets in fact, though there is more in practice. You can make up your own if you want to, but it takes more thought than appears at first glance. It is important that no two words rhyme, so that there is a high probability that they can be properly distinguished even if only part of the word is heard. Intelligibility is the only goal. But that does mean that sticking to a conventional, widely used one is the smartest.
