I don't remember the numbers, I know he mentioned that the only time he tweeted was when he tweeted a series of numbers that the fans decoded (I don't know what he's referring to), then at some point he typed something at the top of the chat and it was just a series of numbers and he laughed, then I had to log off.
Could be Brad being sarcastic I think in one previous chat he said that he only tweeted once through the LP twitter account and that it was so glorious that he couldn't possibly make it up to it and so he'll never tweet again. Classic Brad.
