Here we go with another round of UFO sightings.

Some of the video clips shown in this video are ridiculous, unbelievable and laughable. Others look like U.S. flight experiments & tests.

I don't believe that Earthlings are the only living creatures in the universe, but it's gonna take a lot more than a homemade video of some clown throwing pie plates in the air to make me believe we've been visited by aliens.

Anyhow, it's Monday - sit back, relax and enjoy a good laugh at some of these clips...and wonder about the others!
