When I was a teenager I used to joke that I wanted to set up a phone service: 1-800-FUCK-OFF.

The idea was that when you would call it it would just scream: "FUCK OFF!" at you and hang up, and charge you fifty cents for the privilege.

In my mind I imagined it would spread virally as people dare each other to dial it ("Naw, you're bullshitting, that number doesn't exist!") and that it would have made real money.

An 800 number is toll free, so you'd be paying for everyone calling you. Since you'd have a near zero chance of getting people to enter their CC# to bill them, the only way you'd make money is by selling the numbers that call you to telemarketers.

You could set up a 900 number, which would do what you wanted, but I doubt you'd get as many takers.
