That's when you run open headers at 8 AM after village quiet hours are over and they can't complain about the noise.... You know that if they were up that late, they are asleep early in the AM....
Back in college, I studied for a test the next day. I was up until 2AM and then went to sleep. The guys in the room next to me came in at 4 AM all loud and woke up half the floor, including the floor RA... We all asked them to quiet down many times, and they wouldn't (they were too drunk and cranked up)...
So when I got up for my test, I waited until 8:01 AM, I CRANKED Boston at 100 watts out of 4 speakers including one set with 15" woofers, and blasted them out of bed (they were on the other side of the wall from my room, next to me)... I had the best stereo on campus and they could hear me on the other side of campus... The RA even thought it was classic that I woke them up with pounding hard bass music when they were still drunk/hungover for keeping us up late when we had a test... He couldn't yell at me for being loud, as quiet hours were over, he was on my side...
They didn't do that again....
I wouldn't have minded if I didn't have a big test that day....
