the NSA thing was a joke. conspiracy guys think the government has giant mainframe computers that store every phone call, every site you visit, every piece of online correspondence... so, if they're right, then on some giant underground computer there are copies of all of your phone calls.
that said, we don't repeat call people here. it's one of our biggest no-nos, and for good reason -- it's called harassment, and it's illegal. so you SHOULD feel nervous about calling the people you were harassing and asking them if they still have the recordings -- so you can post them on the internet... so that part was a joke too.
sorry to be a dick, but roy and I got into the pranking thing and we had sense enough to try to be gentlemen about it. not everyone does, clearly, but I'm not inclined to help someone retrieve prank calls that violate my moral sensibilities. nor do I think anyone else here is so inclined.
if I were you, I'd consider them all gone. because in reality, they are. I seriously doubt whoever you pranked would still have the audio files. and even if they did I'm even more doubtful they'd be agreeable to providing them to you.
so let's just start fresh.
haya doin? welcome
