You know, while this is a prank, and it does raise some serious concerns with clogging the pipes (stuff catching on the cable) it really isn’t a bad idea. The last run of cable into the house is one of the most expensive connections. If they dropped in a fiber run and pulled it out at regional sewage taps, it would be very, very inexpensive. I’d put time/money into this Apil fools joke if one could resolve that one concern!
