Nicki Minaj -- Anaconda (The Fart Remix)

Nicki Minaj's "Anaconda" music video is filled with ass -- but now, thanks to the glorious power of the Internet (and some editing software) ... it's also got a lot of gas.

A comedy duo out of South Africa named Derick Watts and the Sunday Blues released the flatulent remix late Tuesday night.

The concept might be is definitely juvenile ... but we dare you to watch it without cracking a smile.

For those who haven't seen Nicki's original -- SHAME ON YOU!!
