So the Bureau claims it would take 20 years to sort the 'good' bills from the 'bad' bills? Maybe I'll send this:
I recently heard of your unfortunate incident involving the Bureau of Engraving and Printing and $100 bills. As a proud American, I'm offering my services to correct the situation. Send a pallet or two of $100 bills to my house; I'd be more than happy to sort through them and send you all the good ones. To keep everything above-board, I must inform you that my error rate may be as high as 1 bill per 500, so I may accidentally retain a few 'good' bills during the process. I'm sure you won't miss them (much...).
