Oh, brain, why?

[offcntr]

So I found myself singing the first two lines of this ditty as I packed up pottery Saturday afternoon. Didn't get any further, but the next couplet appeared in my head this morning, so now I feel like I gotta continue. Brain, why are you like this?

I am the very model of a pottery professional
I spend all day inside a booth the size of a confessional
My record has more mugshots than the average Congressional
I am the very model of a pottery professional!
