Huh?

I had to go to the local stationer's today and the young man behind the counter told me that he'd had a cold call this morning. The person on the other end asked him if he'd got a mobile, and because he didn't want to deal with it, he said no.

Cold caller: How much do you pay for your landline, then?
Young Man: Actually, that's really none of your business.
CC: Mind your language!
YM: What? All I said was - it's none of your business.
CC: none of my business, is it? Look. You live at number X, XXXX Street, Glastonbury. AND I'M COMING ROUND THERE!!!

At which point, the young man put the phone down. He says he's expecting to go home and find an axe-wielding maniac trying to install a cheap telephone line. He tried to trace the company that the caller was from, but couldn't.

You cannot make it up.
