"Do I believe in UFOs? Sure, I believe in UFOs. UFO means 'unidentified flying object,' and I have no problem with the idea that people see things in the sky that they can't identify. It's when they start trying to identify them that I have a problem!"
I see a lot of things in the sky that I can't identify--so to me they are UFO's. I suppose if the guy next door sees them and knows what they are, then to him they become IFO's. LOL!
