Recently the cable guy came by my door trying to sell me any and all services that his company has to offer that I don't currently have.
"I see that you have internet with us. How is it working for you?"
"Do you have a satellite dish? What do you use for tv? You know we can save you money if you bundle your cable with your internet."
"I have an antenna."
(slight choking sound) "An antenna? Interesting..."
"Yeah, it's free. You see it right there in the window, Ahfaz? It looks like a giant pair of rabbit ears on top of my tv. Now take a good look at that silver flag on one ear. You think that's there for decoration? No way. That's aluminum foil and it helps reel in some extra signal. Now if you ever walk by and it's been replaced by a white flag of surrender, then you can come back and sell me your expensive cable in a bundle. Hey, listen, I'd show you my covered wagon, too, but it's in the shop."
