Drawing a blank

I’m trying to write a story, but I’m drawing a blank.
I imagine the blank in my mind, standing there, chewing the creativity out of the imaginative part of my brain to pieces.
I send my guards after the blank, and it is captured.
After torturing a confession out of the blank, I have it dragged out into a field.
Its legs and arms are tied to horses, and I ask the blank if it has any last words.
“Nope,” it says. “I’m drawing a blank.”
“Not me,” I say. “I’m drawing and quartering one.”
The horses pull it apart.
