I'm intrigued by the idea. But I believe we'd both agree that you've lied many times before (even about this issue) and been proven to be full of shit a number of times.
But alas, I have a solution. Let's add a little real-world financial risk to the wager.
1) We mutually agree to an escrow agent who will protect both of our identities. That's easily done.
2) Once an agreement is in place, we send them a little cash... I'm thinking something in the $5,000 neighborhood. We can do more if you want to make it interesting.
3) First one to break the deal gets the escrow.
I'm sure Need2 uses an attorney -- I'd propose he be the escrow agent.
So C'mon pubbie, let's do this.
