Full Brain Shutdown

He thought and he thought
But nothing came in.
A full brain shutdown.
Had he emptied his bin?
Was it some sort of block?
A thinking famine?
Gray matter gone black?
Out of whimsy and whim
Had he finally gone dim?

A last gasping thought held him,
Looking hopeful but grim:

To jump-start something start jumping!
To get those thoughts up and thumping
He had to get himself bumping!
So he bobbled about and, bubbling something,

Hit the floor and broke through
Falling back on into
His brain where he knew
Some thoughts that were new.
