If one famous person is an alien, who do you think it is?

Well, my first thoughts were Steve Buscemi, and then William Dafoe, because there is something non-human looking about them.

My next thought was Robin Williams, but that was more of a joke answer. (Mork from Ork)

Micheal Jackson and Joan Rivers seem to be likely candidates, but I believe the story that they are just normal people getting too much plastic surgery to cling to their dead careers.

My final answer is Christopher Walken. He has been around forever, and he seems to have aged much slower than most everyone. After 50 years, he still seems to get parts in movies, left and right, so there just is something not quite human about him. His voice also sounds a bit synthetic.

Obama.

there is a reason why everyone love him. Also explain how he somehow genetically related to everyone on the planet. The aliens took a bunch of samples from everyone over the years via abductions and then threw them all together to make his body. then they instructed his subconscious to run for president and do everything he'll ever do. They also alter his body chemistry so that it'll make him irresistibly sexy to all the ladies and some men. then they planted him as a baby on Earth, hypnotizing his would-be family into thinking they always had him, and let him loose.

James Randi

Psiexploration

The "Amazing" Randi, who poo-poo's the idea of psychic phenomena by flaunting his one million dollar prize for proof, to his satisfaction, of any "provable on demand" phenomena. What better way to keep psychics under control than to discredit them and convince the general populace to think they are frauds? Psychics are probably the only reliable people who could positively ID him as alien, anyway.
