Adjustable Belief Systems


You know the feeling.  For the 14th year running, Uncle Harry comes to Thanksgiving dinner and recounts how space aliens brought him on
board their craft and probed all of his orifices with an instrument made of some shimmering, otherwordly metal.  You get tense.  You come
close to shouting "ENOUGH WITH THE ALIENS ALREADY!!!", but then the big question hits you:

Why can't *I* believe in UFOs and space aliens?

WELL NOW YOU CAN!
