From the people who bring you Dr. Pepper and 7-Up: flavored milk. It's EXTREME milk!
Oh man, hold me back! Piña colada flavored milk? Why the hell haven't I been putting sliced of pineapple in my milk before?!
Oh yeah, because it would taste like CRAP!
It's milk, dumbass! It's supposed to be bland an boring. And really, what's wrong with just adding some Nesquik to your milk if you want something more exciting?
(Yes, aside from what's wrong with Nestlé in general.)
