"Do you sell mod chips?"
Gord: "Go ahead, ask me what I sell."
"What do you sell?"
Gord: "I sell video games. What a stupid question."
"What does a mod chip cost?"
Gord: "Apparently one of us isn't keeping up."
"What do you mean?"
Gord: "If I sold you a mod chip, then you would never buy a game from me ever again. And that would be very much in opposition to my being able to run a profitable business."
"I just want one to play copied games."
Gord: "What? Do I look like an idiot? What the hell did you think I thought you wanted it for?"
"Err?"
Gord: "Exactly. Now look, if I were to sell you a mod chip I would lose you as a customer. Now, if I were going to lose you as a customer I'd rather do it on a high note like setting you on fire. At least then I would have some satisfaction of a job well done."
"I'm leaving!"
Gord: "But I haven't set you on fire yet!"
