I just had a great idea ....

Throw out the entire batch of the new 100 Dollar bills, reprint them but this time start the serial numbers with "QE"

QE2 for the current round of printing mon... er "Quantitative Easing"

QE3 for the next round implied in Sunday night's interview

QE4 for the next one when these two have failed,

etc. etc.

Based on current series numbering of fiat currency, the FED can print $999,999,900 in 100 dollar bills for each "QEx" Series printed, or 999 Million, 999 Thousand, 900 dollars.... just short of 1 Trillion.
