What began as a simple post on Subway Australia's Facebook page demanding to know why the company's Footlong sandwiches were coming up an inch short has spiraled into a full-blown lawsuit.

John Farley and Charles Noah Pendrack filed court documents in New Jersey yesterday seeking a rebranding of Subway's signature sandwich.

"The case is about holding companies to deliver what they've promised," their attorney Stephen DeNittis told the Associated Press.

According to DeNittis, the suit was filed after footlong subs from 17 different shops were measured, and all proved to be smaller than advertised.

In a statement issued last Friday, Subway said the word "Footlong" should not be taken literally, as it is a trademark and "not intended to be a measurement of length."

But ads produced by the company appear to suggest that customers ordering footlongs should expect their sandwiches to be exactly one foot in length.

In addition to their request that Subway find a way to ensure that all footlong sandwiches conform to their moniker, Farley and Pendrack are also seeking an unspecified amount in compensatory damages.

Meanwhile, in Canada, a woman claims her daughter suffered several oral lacerations after biting into a Subway sandwich that contained shards of glass.
