Thank God someone finally wrote an instruction manual.
There's a long-running Heineken beer advertising campaign in the UK (can't remember if it ever found it's way to the US or Canada) with the slogan, "Heineken refreshes the parts other beers cannot reach." A few years ago, they did a commercial that started out with a stereotypical black blues-singer sort of fellow sitting on his front porch, dog sleeping at his feet, trying to play the blues on his guitar (the man, that is, not the dog). He picks a bit, and sings,
"Woke up this morning, and the sun was shining down on me..."
He looks frustrated, and exclaims, "Dang! That ain't the blues!" And I think he tries a few more verses, but they all come out happy (He's got a good woman, etcetera.)
Then he pops open a bottle of Heineken and takes a swig. Immediately, he hears a thunderclap. The skies grow dark and it starts raining. His dog bites him and runs away. His wife comes out of the house, slams the screen door and throws a frying pan at his head, shouting, "...and I ain't never coming back!"
He starts pickin' away, singing, "Woke up this morning, was trouble as far as I could see..." He loooks quite pleased, and says something like, "yeah! Now THAT'S the blues!"
