The earliest that Jesus could have been born is 7 BC. To keep the math easy, lets start with the entire year of 6 BC. That's (6 X 365) + 1 (got to be a leap day in there somewhere) for a total of 2,190 days.
Then, there have been 2008 years since the beginning of the year 1 AD until the end of 2008. So, making sure we count the 504 leap days (yes, I know that for part of this time they weren't on the calendar) that's (2008 X 365) + 504 = 733,424 days. Adding in the 41 days so far this year we get 733,465.
Divide that into the stimulus total and we find that we are about to spend at least $1.14 million for every day that has passed since the birth of Jesus Christ.
And here's the kicker: If the CBO is to be believed, it will actuallly SHRINK the economy.
I use a similar device, modified thusly: You start a business the time Christ is born. Your business loses $1,000,000 a day, every day, starting then. Six hundred years from now, your business will be 1 trillion in the hole.
