Quite literally, flying. Sommeone linked this in an IRC channel and I just thought it was cool 
Wingsuit Basejumping - The Need 4 Speed: The Art of Flight from Phoenix Fly on Vimeo.
I don't even….what?
This first video is a fairly old account of two European guys who managed to illegally BASE jump off of the then incomplete Burj Khalifa, formerly the Burj Dubai (this is from May 2008 I believe); the video footage they captured during their "flights" is unreal.
Then in January of this year, two guys were given official permission to jump from the building, although I think the above video is cooler 
Old news perhaps, but still pretty cool
I don’t think anyone seriously expected that would happen…

As was kindly pointed out in the comments, this is a clip from a commercial, but I think it’s much more humorous when taken completely out of context.
