That Was Some Pretty Bad Fake Guitar Playing

Always bugs me when an actor is obviously not actually playing an instrument on camera. Also, I had to laugh when it seemed as though he was expecting to derive income from his "album". My god, he's fifty and a nobody! Unless he has friends in the Flaming Lips he's out of luck. Loved the man cave, too. Who is that drawing of?

Then again, everything about this movie made no sense.
