Some guy in the local cable TV offices watches dozens of stations at the same time. When they go to commercial, he pushes a button, and pre-empts the regular commercials with embarassingly low-quality local adverts. They run on a 45 second loop, and then repeat, sometimes 2 or three times before he finishes his cigarette, gets out some more betel-nuts, and then turns the adverts off.

I'm not against the local advertising, but I do object to the fact that they often turn them off late, and you miss some of the actual programming, sometimes minutes of it. These guys have to die.
