In 1989, real estate developer Seymour Durst installed an electronic billboard near Times Square that tracks both America's national debt and your family's share, back before San Francisco destroyed the family. The clock has been modified by replacing the "$" with a "1" to display the current $10 trillion-plus debt level. The Durst Organization reportedly plans to replace the clock with a 15-digit version.

Here's another sign the economy is in trouble: the National Debt Clock in Midtown has run out of digits. The United States now officially owes more than 10 trillion dollars and now the clock's owner, the Durst Organization, has now had to make room for a 14th digit. John Del Signore has another idea: "While they're at it, they may as well make room for a 15th and 16th digit, and change the currency to yuan." [Gothamist]
