Cable stealing goes back to the days where people would watch stage revues in the 1920s through small holes in the wall. These people were referred to as funnery snatchers, and they created an art in stealing entertainment. Theaters resolved this uprising by converting their "swindle holes" into the first glory holes, the first of many times that the entertainment business and anonymous sex crossed paths.
1. The inside man
Being the inside man entitles you to many perks like free cable and coffee. The small price you have to pay is to convince someone in the cable installation industry to hire you in some capacity. Your position could be as lowly as the business's glory hole scrubber (as it is part of the entertainment industry after all.)
2. The blending
You do not want to be that shifty new scrubber who is mysterious to all. You must chat with your coworkers and make it seem like this is your passion. This is to misdirect them from thinking you are about to steal their cable. Do this for 3 months.
3. The asking
Ask your boss/lead janitor about the "free" cable hookup. He will look around to make sure no one is around. Then, he'll give you a number to call. Do not call it from your house or cell because they can trace that back to you.
4. The calling
A woman is going to answer, this means you are doing everything perfectly. If a man answers, yell "THIS WASN'T PART OF THE DEAL" and wait till the next day. Once you get the girl, she's gonna ask for your address. Give it to her, but only in a way you two will understand. I would go with Pig Latin but you didn't hear it from me. She'll make an appointment.
5. The rendezvous
She says this guy is gonna stop by from 10 am to 4 pm. You have to be at your house because this guy means business. This is not a guy you want to fuck with by picking up some milk at the c corner store that's only a block a way. He eats glory-scrubbers like you from breakfast. People have woken up in their grave for worse shit than that. Just play it cool. Once he shows up and you show him your employee card, he'll give you the hook-up.
6. The switcheroo
Now, you can't work and watch TV at the same time, but this conundrum is one of the easiest to solve: hobo labor. Find a pauper who looks just enough like you to pass off as you at your place of work. As long as he remains gainfully employed, you have some stolen cable to enjoy. Also, continue to cash the checks. There is no reason for you not to get paid for brilliant misdirection.
