"Although we are a fully functioning coffee shop, for legal reasons Dumb Starbucks needs to be categorized as a work of parody art. So, in the eyes of the law, our 'coffee shop' is actually an art gallery and the 'coffee' you’re buying is considered the art. But that’s for our lawyers to worry about. All you need to do is enjoy our delicious coffee!"
And all the media need to do is lavish them with publicity... before their lawyers do battle with Starbucks lawyers (and lose).
How far can we go with the "It's an art project" defense?
