I had a neighbor who lived above me in a shitty apartment building while I was in grad school at OSU. The floor/ceiling was so thin I could hear everything he did. Whatever the hell job he had he never came home until about 3 AM. It usually wasn't a problem, except every once in a while he would crank his stereo and let it go for about 10 minutes.
It was the end of finals week and I had to get up early to go to work. He came home and was cranking his tunes. After an hour I went up and banged repeatedly on his door, but he refused to answer. I gave up and called the cops.
As soon as they knocked he answered and shut off the music. The cops had parked their cruiser right under my bedroom window and I heard them laughing as they got in the car. I guess he had a girl with him but they didn't think he was going to get any by the look on her face. I never heard another noise from him again.
The worst part, the idiot neighbor under me thought it was my stereo. That is how loud it was. I had to explain to the building manager I had called the police as it was the neighbor above me. He didn't believe me. Moron.
