First, two signs, each telling a very different story:
This sign says, "we're in power, we're going to use newspeak and double-talk and pretend we've done something to benefit you, which of course, we haven't." It also uses "conveniently" as an adverb, which is just annoying. Why not tell the truth, straight up?
On the other hand, this sign screams transparency and honesty. The farmer explained that on days when the corn was picked that day, he erases the scribbles on the bottom of the sign, but if the corn was picked just one day earlier, it's just not right to say 'fresh'. It's worth noting that instead of having two signs, one for each condition, he uses his own hand to tell the truth, quite vigorously. Guess who has the most popular corn stand in New York, even on days when it is not, apparently, fresh?
