We've seen a lot of videos that are plain stupid but pure pleasure for the weird soul in us. From effortlessly cutting sand to gross ones like people digging out earwax, there's no guessing to what pleases us. 

A video of a guy polishing a rusty knife is taking the internet by storm. Uploaded by Jun, this video is already among the top videos on YouTube. Having bought an old rusty knife for $3, he goes on to polish it well enough to make the seller regret his decision. And while he is at it, his cat looks on with the composure of an ice queen.
