Reminds me of a story... My best buddy in college had this old cd player in his car, which after a few years became defective ina a very peculiar way: It would increase the volume, very little by little, with every bump on the road.
So inevitably, every 10 minutes or so we would find ourselves shouting over our lungs to carry out the conversation without realizing it, and then finally be &%^$%!$%#!! and turn the volume down manually. This cycle repeated itself every 10 mins or so, it was frustrating and hilarious at the same time. The fact that it was a very small increase every 20 secs or so was wad made it so miserably EFEFCTIVE.
