Peyton Manning can't quit shouting about Nebraska's largest city.

The Denver Broncos quarterback used the word "Omaha" loudly and often during Sunday's NFL playoff win over the San Diego Chargers. Its meaning, if there is one, is known only to the Broncos.

It provided unexpected publicity for the city of 427,000, which is perhaps best known as the home of billionaire Warren Buffett. Omaha was a trending topic on Twitter during the game. By one count, Manning uttered "Omaha" 44 times.

Greater Omaha Chamber of Commerce president and CEO David Brown says he wants to explore the possibility of hiring Manning to shoot a promotional ad for Omaha, though the quarterback's fee might be prohibitive.
