I do know that this is funny, in sort of the same way that Sarah Palin is/was funny - - it's comic gold, but somebody somewhere thought it was a really good idea and not funny at all. Which is frightening and somehow adds to the funny. Very meta.
However, unlike Sarah Palin, I am not laughing at these guys, I'm laughing with them. Because even though some of them are looking at their music as if to say, "What am I singing and why am I even here?!?," these motherfuckers are rock stars!
