Balls and chops

1. Do you keep the dog in the kitchen or does
he have the run of the house? Is he restricted to
one area or can he go everywhere? Merriam
Webster online: RUN 2 a : to go without
restraint : move freely about at will. Let chickens
run loose.

!!!
Thanks a lot - I've completely missed that out.
so, "we're to give him the run of the farm"="we're to allow him to move freely at our facility"

2 : a house or apartment open for inspection
especially by prospective buyers or tenants

Yep.

And the next one - Anderton has a conversation with a drug dealer in order to acquire some stuff:

"- Don't bust my balls. You've only given me four, and some of these are duds."

"Don't bust my balls"="don't spoil my pleasure"?

Balls refers to testicles. But you probably knew that. It's not about pleasure -- it's more about status. I would say that busting someone's balls is to humiliate the person, take away his or her power or standing. Emasculate him (or her). Anyone have a better explanation?

And sometimes doesn't it mean hassle someone, give him or her a hard time, the "run around"?

I think busting someone's chops is the same idea. Maybe chops is a polite way of saying it.
