I came up with puzzle, I think it's clever.
Two women, Eve and Amy, sit at a table. After a bit of casual chit chat. Amy, writes on a piece of paper and says “I wrote five words. It is a true statement, but I bet you five dollars that you will read a false statement.” Eve accepts the bet and reads the paper. She loses and pays Amy the five dollars, but Amy did not lie.
The phrase was not based on the person who wrote it or the wording Amy used, and later if Eve wrote the same five words and made the bet to someone, Eve would have won. What was written on the paper?
