A recent reading by Brookland Area Writers and Artists included this poem by former poet laureate Howard Nemerov, which I thought a great example of poetry using humor to skewer jingoism.
TO THE GOVERNOR & LEGISLATURE OF MASSACHUSETTS
When I took a job teaching in Massachusetts
I didn't know and no one told me that I'd have to sign
An oath of loyalty to the Commonwealth of Massachusetts.
Now that I'm hooked, though, with a house
And a mortgage on the house, the road ahead
Is clear: I sign. But I want you gentlemen to know
That till today it never once occurred to me
To overthrow the Commonwealth of Massachusetts
By violence or subversion, or by preaching either.
But now I'm not so sure. It makes a fellow think,
Can such things be? Can such things be in the very crib
Of our liberties, and East of the Hudson, at that?
So if the day come that I should shove the Berkshire Hills
Over the border and annex them to Vermont,
Or snap Cape Cod off at the elbow and scatter
Hyannis to Provincetown beyond the twelve-mile limit,
Proclaiming apocalypsopetls to my pupils
And with state troopers dripping from my fingertips
Squeaking "You promised, you broke your promise!"
You gentlemen just sit there with my signature
And keep on lawyer-talking like nothing had happened,
Lest I root out that wagon tongue on Bunker Hill
And fungo your Golden Dome right into Fenway Park
Like any red-celled American boy ought to done
Long ago in the first place, just to keep in practice.
