While checking out at the grocery today, the clerk rang me up and gave me the total. I then pulled out the paper notes and said, here is a Jackson, a Hamilton and a Lincoln.

The clerk then said she was recently watching a television game show and one of the questions was, "Which president is on the five dollar bill?" She said the game show participant did not know the answer.
I then replied, "They also don't know their own name and can't remember where they parked the car". I thought she was going to bust an artery laughing.........
