Found this article a couple of days ago - I think some time Wednesday - while typing random things in to the search engine when I was "between activities" (not exactly bored, but not really having any idea what I felt like doing). It's from a couple of months ago, but thought I'd share it anyway. I think it was from The Daily Telegraph's web site.
Note: 999 is our version of 911 (for those who don't know).
Moon mistaken for UFO
Police in Wales were called to investigate a mysterious flying saucer, only to discover it was the moon.

The moon was mistaken for a "bright, stationary" UFO which had been loitering for at least half an hour, by a confused local in South Wales who made a 999 call to the police.
Today officers released a transcript in order to highlight the time wasted by unnecessary 999 calls.
The bizzare conversation ran as follows:
Control: "South Wales Police, what's your emergency?"
Caller: "It's not really. I just need to inform you that across the mountain there's a bright stationary object."
Caller: "If you've got a couple of minutes perhaps you could find out what it is? It's been there at least half an hour and it's still there."
Control: "It's been there for half an hour. Right. Is it actually on the mountain or in the sky?"
Caller: "It's in the air."
Control: "I will send someone up there now to check it out."
After the police patrol car arrives, the script reveals the exchange between the control room and the police officer sent to the scene.
Control: "Alpha Zulu 20, this object in the sky, did anyone have a look at it?"
Officer: "Yes, it's the moon. Over."
A police spokeswoman said: "This was a recent example of an inappropriate 999 call to South Wales Police. "Yes, we can all see the comical side but calling 999 with an unnecessary non-emergency call could block a genuine call for vital seconds and put lives at risk."
Other bizarre calls cited by the police force included someone asking for help voting for Rhydian on The X-Factor and another requesting a pound coin for their supermarket trolley.
