I don’t waste too much time on the UFO stuff, But I do enjoy when they come up with some of the nuttier stuff, it gives me a giggle.
Like there’s one guy who claimed he had photos of the aliens. The “alien photos” turned out to picture he snapped from his TV screen of singer-dancers on the Dean Martin Show.

And people actually believe this stuff. Oy.
