Turtleseed has a weird fascination with Nebraska, and specifically corn. Every so often, the entire shore becomes polluted with posts about corn and Nebraska, talking about how evil it is.
Never go to Nebraska.
It is possible that this meme is linked to the frequent use of potatoes to comedic effect on Turtleseed, a period that can be divided into at least Potato Eras (December, 2014 Potatoes and May, 2015 Potatoes). It may be that this meme is more closely tied to Idaho or Ireland than Nebraska, but all three a pretty rural and full of tall grass or whatever countryfolk eat and build their houses out of.
Never go to Idaho either.
