Backwards Running Competition in Reverse Video
There a thing where runners compete by running backwards. Someone thought to take footage from one of these races and reverse it. The result is positively spectacular.
Mind you, I'm easily amused so I couldn't get enough of the reversed footage. YouTube user WerkProof also shared this bit of magic where firefighters slide up the pole.
In case you missed it, I ate a banana in reverse and enjoyed it far more than I should have.
