Subway has a nice knock-down argument against length complaints

Subway says "footlong" is just a descriptive (um, wouldn't that be deceptively misdescriptive?) trademark, not a statement about length.

'When I use a word,' Humpty Dumpty said, in rather a scornful tone, 'it means just what I choose it to mean — neither more nor less.'

'The question is,' said Alice, 'whether you can make words mean so many different things.'

'The question is,' said Humpty Dumpty, 'which is to be master — that's all.'
