"When motorists snapped photos of the strange object and posted them on Twitter, some people became concerned enough to call local police."
It was actually a military drone.
[Pet peeve: UFO stands for Unidentified Flying Object. It's not (necessarily) an alien spacecraft. Even if this was one, it couldn't be a UFO because it wasn't flying!]
"One man called 911 in Prince George's County because, he said, he was concerned about a relative who lived along the route."
That is, the guy didn't call 911 because he saw the "UFO": he called because he read about it on Twitter.
Other stupid 911 calls made recently:
- A strip club wouldn't let a man enter with a kitten.
- A deli made a sandwich wrong.
- A Hardee's hamburger tasted bad.
- Gas is too expensive.
- A man's wife wouldn't stop looking over his shoulder while he was on Facebook.
