I know you're joking around, but I thought it was interesting. There is also apparently a large "atomic bomb sized or larger" impact about every 1200 years (the last one being Tunguska in 1908, so hopefully we are fine for a while).
Although the same story said that ones equal to Tunguska could have happened more often and new just didn't get around, or the stories were not preserved.

Plus they think it was only one meter in size which would make it very, very difficult to detect.
I think NASA is doing a great job at detecting them considering the limited funding they get. (The US military spends more on air conditioners then the entire NASA budget).
They have a really good idea on the all the planet killers. (like of the one that killed the dinos) We are safe for at least 100 years.
Smaller ones like the near miss that is going to happen later today could pop up with not too much warning. Those ones are not planet killers but could devastate a 2000 KM square area.
