My dad would take the modem with him to work, and when he was at home using the internet he would turn it on, wait for it to boot, load a web page, and then turn it back off until he needed to load another webpage. That was the only way he actually stopped me from getting to the internet, but it was a too much effort and he didn't keep it up for long.

Statute of Limitations, but...

A "friend's" parents chose to go without a phone. My "friend" realizing how simple the old phone systems were rewired the second line of "his" parents' house to the line of a neighbor from a near by junction between houses. "He" would have to quietly pick up the phone to see if the line was free, and quietly hang up if not to try later. It worked well for a period of time until "he" forgot to unplug the phone before leaving. "His" parents were quite surprised when the phone in "his" room started ringing.

Oh man. I too have a "friend" with a similar story. Except my friend was connected to a pay phone line at a nearby store and managed to route the line all the way into his bedroom via existing unused pairs along the way. All so that he could dial into long-distance BBSes. (Because there were none locally.)

Eventually the phone company caught on and probably _could_ have charged my friend with theft of services or something, but instead just disconnected the rogue line and put a lock on the payphone interface box and placed a large "property of the telco" sticker on it. Probably dodged a significant bullet there, in retrospect.

I would be proud of my kid if they did that. I would ground them, but proudly.
