I've found it. Proof that aliens are here on the planet. Compare these two pictures. One is a real alien skull. (Yes, it's real, I found this picture on the internet with the caption "Real Alien Skull." That's all the proof I need.) The other, a profile of Victoria Beckham. Coincidence that they are perfect matches? I don't think so. Go with your gut on this one. You've noticed how Posh Spice isn't "quite normal" haven't you? How she is always a bit too perfect. Like she doesn't ever look like she lives, but that she is just there. Stilettos every second of every day, not one hair out of place, beautifully perfect clothing at all times. She is masquerading as a human to collect information for her distant planet as well as guarding Earth's most treasured possession, David Beckham's right leg.
Let this be a lesson to us all: Those conspiracy nut jobs are right! Aliens are here. And if they are right about that, they're probably right about everything! (Except the moon landing, Mythbusters busted that one.) Denver airport is a New World Order prison facility/underground bunker. Smoking doesn't cause lung cancer, it protects us from airborne radiation. The US did bring down the twin towers with missile-armed airliners and Lee Harvey Oswald didn't act alone, he had helper buddies at the grassy knoll. (Well maybe not the JFK one, that's just crazy.)
What do we do with this information? I'm not quite sure at this point. But if you ever run into Mrs. Beckham treat her with the utmost respect. If I were you I'd give her a knowing look while slowly nodding my head and then submissively bowing. I'm pretty sure aliens are friendly if we just let on that we know they are superior and we're okay with it.
