Fifth Third Bank TV Commercial, 'Proven Mathematically'

Fifth Third Bank is working hard to make banking a fifth third better by putting 166.7 percent into everything it does. Even when a mathematician says that, technically, you can only give 100 percent, a Fifth Third banker proves her wrong, pointing out that the bank has a state-of-the-art mobile app, fee-free ATMs and great customer service. The mathematician can't help but admit that she stands 166.7 percent corrected.
