How Can Something So Cute Be So Disturbing?

I love the M&M commercials with the CGI M&M "people." There's a new one out that starts out innocently enough with a pink peanut M&M "woman" reading a paper on a park bench when an adorable CGI squirrel sits down in front of her. She smiles at the cute sight, and then returns to her paper, only to look down again a moment later to see a whole horde of squirrels. Then the squirrels ATTACK HER EN MASSE (because she has a peanut center) and the last thing you hear is her scream of terror as she is presumably EATEN ALIVE BY SQUIRRELS!!!!!!! Stuff of nightmares right there.
