Spinal Tap - One louder than any other band.

This is Spinal Tap is probably one of my fathers favorite movies. The dry satire and punny nature of the film coincide perfectly with my fathers humor. Naturally, the first time I saw this movie I was quite young, and most of the humor went right over my head, actually the whole movie went right over my head because I had thought they were a real band. Since then I have seen in numerous times and the mocking nature thusly became evident. My favorite scene, that I  laugh at every time I watch it is the "up to 11" part. (Below)

The sheer stupidity and thick headedness of these scene, for me, sets the tone of the entire rest of the film. Essentially it gets me into a ridiculously silly mood.
 Recently, my father told me that even IMDBs rating of spinal tap is out of 11!
