Back in High School in the 90s we had to watch this thing called "Channel One" before class. It was a really bad newscast that had commercials in it. By some miracle the school used the same brand of TV (Magnavox) that I had at home.
At one point I started sneaking my remote in, and would surreptitiously turn it off in the middle of the newscast. I'd do this every day, making them think the TV was malfunctioning. They even called the company to check the TV, which of course had nothing wrong with it. I started messing with the volume too, turning it all the way up or down.
Eventually the teacher got tired of it and we didn't have to watch the thing for the rest of the school year. TV was unplugged. 🙂 I was never caught, and I never told ANYONE, not even classmates. Bwa ha ha ha.
