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. (Search for "Motorcyclist Saves Cup." He grabs the cup at :30.)
