When I was a kid, I always thought breakfast for dinner was a top thing. Of course, breakfast in those days was 3 bowls of Fruity Pebbles (tm)--essentially a bowl of candy with milk on it--so you can imagine why my nine-year-old brain would have delighted at this. That being said, I think it's more than nostalgia that draws us to the occasional dinner-time switch-em-up; there's something taboo about eating a meal at the wrong time. Or maybe it's just that breakfast is awesome, but we don't take the time to go all out very often--so we occasionally have to use our prodigious dinner energies on a breakfast.
This dinner-time inversion was our famous Southwest Scramble.
