Discovered Clerihew

Reading Paul Fussell's Poetic Meter & Poetic Form (an excellent book for those who wanted to know more than they wanted to know about... poetic meter and poetic form), I read this example of graffito (absurd singular not added, but in the original):

"Soldiers who wish to be a hero
Are practically zero.
But those who wish to be civilians,
Jesus, they run into the millions."

Fussell introduces the poem to point out the value of Trochaic substitution. Jesus, in the fourth line, is a trochee (its first syllable is stressed, as opposed to an iamb in which the last syllable is stressed). This draws our attention (as does the fact that it's a the-tiniest-bit-naughty interjection). (Fussell doesn't mention that soldiers, parallel at the beginning of the first line, is also a trochee; the omission makes me wonder if he doesn't pronounce it as an iamb.)

But what he doesn't mention is that this is a Clerihew. And an excellent one at that. Because there is no prescription for meter, poets in the form cannot fall back on anything and have to find utility in the arbitrary; this anonymous has.
