Lunacy (thing)

If I yam me,
And Mi yams I,
Someone will get
A yam in the eye.
If the yam protests,
Then we shall see,
Who I am,
and I yam me.
If Mi likes hymns,
and he hates me,
Then I yam Hymn,
and he is Mi.
Me is hear,
and so yam I,
I eye hymn there,
and he says high.
"High" says Hymn,
and looks at my I,
for hymn is Mi,
and I yam Hi.

Hi, knot high,
as a fool would "C,"
four I yam hymn,
and he is Mi.
