How Not to Make a Cardboard Fort

I found an empty cardboard box.
I made myself a fort.
I had to squeeze and twist and turn
and crumple and contort
to climb inside, but now I'm quite
embarrassed to report
I'm stuck inside this cardboard box
that's clearly much too short.
Has anybody got a box
that's bigger than a quart?
