IU wasn't even talking to you or about that, but no you've pissed me off.
If you don't think This is Spinal Tap is funny, then you have a horrible sense of humour.
If you don't think the merabers of the "band" are absurdly talented, then you don't know anything about them or possibly music.
If your post is totally serious, then you have no idea how funny it is. It's a Mocumentary dude, they're not a real band, it's an SNL cast meraber, the guy who does 1/2 the Simpson's voices and the guy who writes and direct all of the improv fueled films in the Spinal Tap ilk.
By the way, since we don't know each other, no offense just making a point with hyperbole.
