Lets try to count to a thousand. The rules are simple. You reply to the post above you by adding a number until the thread reaches 1000. You can reply to the thread multiple times but you must wait until another user replies to you before you can put forth another number.
So, I'll start with 1.
Someone will then reply 2. Then another user will reply 3. So on and so forth until it reaches 1000.
I've seen this done before but I've never seen it ever reach fruition.
