Seriously, do you have a home theatre system? With a subwoofer?
Just play movies with the subwoofer on only.

The ELF track will really annoy alot of people. But this is willful meanness.
As easy as it is to come up with these ideas, I always think it is less rude in reality to just go and have face to face confrontation with people. Unless of course they are just wackos.
