If you haven't seen it, there's a video from a couple months ago that's making the rounds online.  It's a guy on a motorcycle who notices that the woman driving in front of him left her COFFEE CUP on her bumper.

And somehow, he manages to swing past at a pretty high speed, snag the cup, follow the woman, and give it back to her...all while they're both still moving.

He grabs the cup at :30
