I remember seeing this dairy-themed rock opera parody when it was first released in 2009 and features "White Gold" attempting to rescue his beloved from an evil megalomaniac with the help of the mythical Bovinia, all the while promoting milk's health benefits. It was originally created as part of a rather exuberant marketing campaign by the California dairy council and has a heavily pun-filled script that I found to be hilariously awful, if not quite awfully hilarious. Anyway, I can think of worse ways of spending 22 minutes.
