Google searches seeking to verify the above video's authenticity have yielded nothing but links to other sites asking the same questions we have, so we're quick to assume this is yet another "viral" marketing campaign for some new movie or TV show.

Update: It's a Ghostbusters III thing.

Rumor has it Columbia Pictures is quietly putting together a script for a third installment of the Ghostbusters franchise. Hoping to bring back the original cast, which included Bill Murray, Dan Aykroyd, Harold Ramis and Ernie Hudson, the studio has enlisted top-notch producers of The Office to write the new script.

Obviously this would be huge, but would it kill Hollywood to pass up a money-making opportunity to preserve the awesomeness of the classics?

It's a slow holiday, a perfect time to debut our first (and possibly final) installment of Lookalike Showdown.

Does Fred Thompson look more like Dan Aykroyd as Judge Alvin Valkenheiser than Bono does a monkey wearing glasses? You decide.
