My neighbors dog dosnt stop barking so I downloaded the fog horn app on my droid. I face my compuer speakers out the window full volume and play the foghorn into the microphone...... They got the hint!
What's the context? One time when I wanted to annoy the people downstairs, I went in FL Studio and put one long never-ending bass note, turned my $600 subwoofer up all the way, and played it while I took a 15 minute shit.
