Nails

Even the most mundane objects, like plain old nails, can be imbued with personality in the hands of a patient and talented animator. There's no need for dialogue in this film, because the movement and the music tell a story. Or several stories.  

Nail is a 1972 stop-motion short by Estonian animator Heino Pars. Since we tend to think that all nails look the same, the YouTube description makes it clear that the film is a series of unrelated sequences involving different nails, so you shouldn't even try to discern a plot that connects them. The first is a love story, followed by a work story, and then a drunken street brawl leading to a magnetic arrest. (via Boing Boing)
