At the desk one day, the topic of how to pronounce the name of the country Qatar came up. No one knew for sure, we'd all heard multiple pronunciations, and the more we talked about it, the more people got involved.
If you search online, there are lots of pronunciation suggestions - most of which are different. Oddly, the State Department's Qatar page doesn't have a pronunciation guide, neither does the Qatar Embassy or Qatar Tourism websites - but the CIA World Factbook does (under the Government section).
Probably the most helpful thing are the audio pronunciation guides, which I found at Wikipedia, Merriam-Webster Dictionary, and NPR (although the radio transcript itself is just humorous).

Of course, that means that Freddie Washington's pronunciation might also be the best guide:
