Why Does The Milk Taste Sour?

The sour milk/sour skittles spot is the latest I've seen depicting this absurd little fantasy land. In the skittles world, you fix a skittles leak in the ceiling by hanging a little man underneath to eat the falling candy, rabbits can sing, creepy English lads dance for berries and cream, and long beards act as appendages. All I know is I want in. I figure the only way to do that is to grab a bag of skittles and lace it with some LSD. I'll catch you guys after I come down.
