freeztar Posted January 9, 2008 Report Posted January 9, 2008 If I told you which one to believe, would you believe me? :) Quote
Tormod Posted January 9, 2008 Report Posted January 9, 2008 Which one do I believe? 1 in 40 or 1 in 28?? I think it's more like 1 in 405. Or was it 3 out of 4? I don't remember. Maybe we'll just have to wait and see which odds were correct. :) Quote
