On receiving two identical emails with the subject line "Blah"

One blah arrived and then there came

A second blah; twas just the same!

I searched my heart, my spleen, my knee

Why had two blahs befallen me?

What strange event, what dire misprison

Had said to two blahs “Be ye risen!

Though courage shrink and wisdom fail

Go both ye forth, ye twain e-mail!”

Perplexed, I went to ask the Shah

What could it mean, this double blah?

The Shah, a man of noble mien,

Was sipping from a brass tureen.

He bid me speak and have no fears

Though he’d been dead for thirteen years

I asked him plain: What should I do

With blah ‘clept one and eke blah two?

His fingers drummed his shaven pate

He said “My son, or soon or late,

To peasant, poet, saint and sinner

Asleep, awake, or over dinner

Reciting life’s do re mi fa

There must come the ill note blah

Why is this and whence come blahs?

No one knows, not even shahs.”
