One day in 1958, when Top Hat chains were operating in several Oklahoma cities, lawyers informed founder Troy Smith that Top Hat was already a copyrighted name and that he would have to make some hasty changes. The chain's partners searched for a name that summed up the company motto: "Service at the Speed of Sound." They decided that the name Sonic had a spiffy ring to it.

Sonic is now the country's fifth-largest hamburger chain, boasting some amazing statistics. For example, if you were to take all of the hamburger patties Sonic served last year and stack them up, they would be as tall as 2,576 Empire State Builidings stacked one on top of the other. Which guy with too free time figured that one out?

If you like your burgers with a spicy kick and dig mustard, try this reduced-fat clone for one of Sonic's tastiest creations.
