Puzzle

I woke up with the worst hangover in my life.
I popped two aspirin, made coffee, and sat down at my kitchen table.
There was a box there.
I opened it and dumped out a bunch of weirdly-shaped little bits.
A jigsaw puzzle?
Oh well. I’ve got time.
So, I tried my hardest, but damn, none of the pieces fit together.
After two hours, I used up all the pieces, but it looked nothing like the picture on the box.
That’s when I realized it was a Corn Flakes box, and I’d just tried to solve my breakfast cereal.
