How many emotions can you experience in seven seconds? This video of a sheep with a bloodcurdling human scream, posted with no explanation, will help you find out.

Sheep are usually considered to be docile creatures, but this one's got issues. Is it suffering from existential dread? Is there a terrifying creature sneaking up behind the cameraman? Or has the poor darling just watched too many movies featuring the Wilhelm Scream? Perhaps that's just its natural voice -- the Gilbert Gottfried of the sheep world.

Regardless of the cause, there's a funny primal weirdness to hearing an animal make a human-like sound. First you recoil in alarm, then you laugh your face off. We'd love to see Screaming Sheep get into an argument with Screaming Goat (watch out, though: he spits).
