1-347-514-7296 is a phone number that automates this. Add it to a conference call, and frustrate the caller with no additional work. http://Reddit.com/r/itslenny is the closest thing it has to an official site.
You do have to get whitelisted though, last I checked. I was able to use it one time and now if I call it I get a message about whitelisting. Same for JollyRoger.
