Does Tom Cruise make you believe in UFOs?

The current poll over at CNN asks, "Do you agree with Tom Cruise that aliens exist?" Currently the split is 60/40 yes in a purely unscientific poll. But I would be more interested to know how many people agree that aliens exist because it's Tom Cruise who says they exist, and which celebrity would cause the biggest spike in belief.

Of course, these polls would be worthless and only mentioned as trivial party fodder, but it'd be kind of interesting to know if anyone would change their mind because, say, Jessica Simpson or Christian Bale says so.

I know it has nothing to do with anything. I'm just saying.
