Many Earth years ago, one of my sons was 5 years old and made a color copy of a $1 bill (both sides), cut them out, and taped them together. As an added bonus, he wrote “20” on each corner with a green marker then tried to present it to me.

After telling him about counterfeiting and the various problems, I added that it wouldn’t even work because most people would look at it and know instantly it was counterfeit.

“But I don’t have to fool all the people,” he responded, “I just have to fool one person”.

That left me thinking for a while.
