If you answered, "Regis Philbin," I'm sorry. The correct answer is "The United States Twenty Dollar Bill," and now you owe me one.
What's funny about Andrew Jackson being on the $20 is that when he was president, he was vehemently opposed to both the National Bank (the Revolutionary Era Bank of North America) and to paper money. The main goal of his administration was to dismantle the National Bank. And he decried the use of paper money in his farewell address. (As a nation, we began using paper money during the Civil War, when metals used for coins were in short supply.)
So naturally, we put this man, who hated paper money, on paper money.
Now we are engaged in a debate about taking his image off the double sawbucks, and surely Old Hickory would approve. There's a push to replace him with a great woman in our history, and if there is a shortage of twenty dollar bills in many pockets, we have no shortage of worthy women.
