Can YOU guess who is underage???

Generally speaking in Australia for Bartenders...it is usually pretty easy to work out who is over 18 and who is not, but in the U.S the legal drinking age is 21, making it just a little bit more difficult to work out who can drink and who can't without seeing some I.D

I must admit, being a former Doorman of a night club, I was pretty much spot on with most of these individuals real ages, who many can you guess correct??
