Get back at your noisy neighbors by playing the Revenge CD. Have a big party (track 2), play the drums (track 5), or invite over a newborn (track 15) just as your neighbors are finally going to bed around noon. The CD comes with ear plugs so you can take a nap while you keep everyone else up for a change.
Oh I wish I'd had one of these when I lived behind a building that hosted a Primal Scream therapy group.
