I remember when I was about 10 years old and Radio Shack had kits for crystal radios and all kinds of cool electronic stuff that fascinated me and I spent my lawn mowing money on. I hooked up a DC motor and some other weird stuff, I don't remember what I thought I was building but it scrambled the living room TV. This was when it was broadcast over the air, no cable at all, no satelite. I had so much fun pissing my Dad off with that little machine I made. I could hear him yelling "god damn it, here it goes again". He'd get off the couch and start banging it, which was the common TV fix back then.
