We were sitting as inconspicuously as possible in chairs towards the back of the room and taking in the work going on around us, when I overheard the following conversation between two little boys as they prepared to count out change from the pretend cash drawer:
Boy #1, picking up a five dollar bill: "Hey! Is our new president on this?"
The two of them inspected the five spot:

Boy #2: "That's not him. He's on the One."
A one dollar bill is extracted from the cash drawer and intensely scrutinized:
Boy #1: "That's not him, either. He's must be on the Twenty."
Two small heads bend studiously over a miniature twenty dollar bill for a solid minute before the following conclusion is reached:

Boy #2: "That is definitely not him."
Boy #1: "Yeah, I guess they didn't get a chance to put him on yet."
(Maybe tomorrow, kids.)
