Continuity mistake: During the "Midnight Express" scene, Chip opens his shirt and presses his chest against the glass. The shot moves to Steven, and as we pan back to Chip, he is sitting, phone in hand, with his shirt buttoned. (01:09:05)
Continuity mistake: When Chip's talking to Steven through the glass, after he stops talking about the Midnight Express, you can see he has no phone in his hand yet when Steven's telling the guard to arrest him he has the phone in it. (01:04:05)
Continuity mistake: When the cable guy puts chicken skin on his face, the bit over the right side of his forehead disappears between shots.
Answer: Earlier in the movie during a flashback of the Cable Guy's childhood, when his Mom was going out she called the television "Mr. Babysitter". He means he's going to disrupt the television signal to give all the boys and girls whose parents use television as a babysitter a chance.
