How should I go about convincing the world that only a small cult believes the silly 5/21?

I think since there are only a few days left you let them be on their own and then when 5/21 passes, ask them (Even though they knew for absolute fact that the world was going to end then. Could their sources what ever they were have been mistaken?) The Christians of course will tell you they simply misinterpreted the bible and then go merrily on their way till Dec. 21, 2012 and then go through it all again. It must be such a grand feeling that no matter what the bible says it is always 100% accurate
