We're Waiting

The latest news from the stars:

SETI Astrophysicist Craig Kasnov (not to be confused with Craig Kasnoff) has announced the approach to the Earth of 3 very large, very fast moving objects. The length of the "flying saucers" is in the range of tens of kilometers. Landing, according to calculations of scientists, should be in mid-December 2012. Date coincides with the end of the Mayan calendar.

So what's taking them so long?
