David Cho sent me a very amusing link. Click on I, II and III. If it's no longer the first entry, scroll down to "Anti Gay Phone Company".
Eugene Mirman, a writer, performer and filmmaker, doesn't quite have the 411 on these calls - what the company is, where the money goes - and I guess he's not inclined to research it. But the phone call are real.
Thanks to Mr Mirman - and thanks, David!
