A day will come when Grace shall reference Tedd's explanation of corny AND IT SHALL BE GLORIOUS.
I'm about to jump into spoiler territory more significant than Grace talking about corn, however, so fairly warned be ye.
This entire part of the Night Out story arc has much greater signficance in retrospect. There is an aspect of Tedd's character that is addressed much later on that really does feel less like grand revelation and more like confirmation after reading through these old comics again. Granted, I didn't know of a word for it prior to I think 2014 (2013 at the earliest), so it's no wonder it took some time.
