WASHINGTON—During a press conference Monday, Treasury Secretary Henry Paulson unveiled this year's shipment of brand-new $2 bills, all of which will be sent directly from the U.S. Mint to the nation's grandfathers by month's end. "I'm willing to speculate that most of you have never seen one of these before," a grinning Paulson told reporters Monday, while gesturing to a sheet of 500 $2 bills, assuring those present that grandfathers everywhere will soon have the perfect gift for their grandchildren's birthdays, good report cards, or just for when they come over to visit. "You can spend them on Lemonheads or anything you want." Throughout the presentation, reporters politely feigned excitement, and afterward they impressed the secretary by accurately guessing whose face was on the $2 bill without having to look at the name printed below it.
