By What Warrant

do we assert that the following limerick was fashioned by President Woodrow Wilson:

I sat next to the Duchess at tea--
It was just as I feared it would be:
Her rumblings abdominal
Were simply phenomenal
And everyone thought it was me.

...and while I am at it, let me revivify a couple of my own favorites (not coined by me):

I once knew a man from Poiteau
Whose limericks stopped at line two.

...and:

I once knew a man from Verdun.
