Sludge in the Old Brain Pan!
Mainline coffee, but sometimes it has zero effect
Can't jumpstart my head; but my heart is racing!
Stray thoughts flitter through my brain, and are lost
Just as quickly as I think them; which is probably
A good thing, because my thought process is skewered
Towards the round-file end of the spectrum
Rev the brain engine, but it makes only a clunking sound!
