Poet Poe pens nonsense verse.
"Plus...phun," puns Uly, "I disburse."
Its gamut runs from spam to worse.
The po'sy posted...? Poe's diverse --
most, postcards from his universe,
replies to grudges he must nurse.
My summary...? Let me be terse:
a mitzva, mostly. (Not a curse.)
For 'semisphere of lead' (one mere- ly micrometers wide)...? I'd pen a 'B'* (halv'd 'BB', si...?), though Bs ain't bona fide. * Not referenced is the British Broadcasting Corporation.
