De-FENCE! De-FENCE!
My overworked brain chants silently
So loudly I wonder if the crowd can hear me
The expert panel is not amused
By my internal perfidy
I’m the bulls-eye and they the darts
With questions they proceed to stick me
Stung so long I start to feel numb
One question, in particular,
Drones on and on
So long I start to daydream
Why does this take so long?

Who am I?
