This only seems like an official video, which just makes it that much more awesome:
Produced by a group known appropriately as Satire, the video plays off of LMFAO's hit, "Sexy and I Know It," purporting to show the NASA Mars Curiosity team showing their stuff. And whoever made the video really has done their homework about NASA operations -- and succeeded in making the agency relevant in a way no form of official communication could hope to do.
The best part, to me, is when the NASA "employees" specifically call out their counterparts in the private space exploration business: "We're better than SpaceX and we ain't afraid to show it!" That may be a YouTube first: pro-government trash-talking.
