If he's directly above you...
Hmmm...
I wonder if you could rent a jackhammer, take off a ceiling fan or light fixture, or somehow temporarily expose one of his floor joists, hang the jackhammer from the joist and run it for a minute or so, just enough to shake all his dishes from his cupboards, the crap off his tables, and the pictures from his walls. Maybe do this while his bass is booming.
Unreasonable people are just begging for a Mel Gibson style response. ;-)
