Well, you've missed Y2K and the Mayan 2012 

Bound to be another end of the world prediction coming around soon for the Ark though.

You've got form at least, Noah was meant to have lived to 950ish, you may need to start work on the full size one fairly soon, or at least make a bigger kitchen table to build it on.
