Repost: What Are The Odds...? A Nominal Anomaly

Though an 'even''s seen in 'seven,' 

oddly, 7 isn't even.

That an 'even''s in 'eleven's odd: 

11, too, ain't even.

An "An 'even''s seen in 'seven,' 

although 7 isn't even"
seems, routinely, a fifteener. 

(Even so, 15's not even.)

An "An 'even''s in 'eleven,' 

though 11 isn't even,"
seems a byzantine fifteener. 

Still, 15 remains uneven.

(Note: these lines through which we plod
though, 'even's notwithstanding, odd,
we see wind down -- for which, thank Gawd! --
and roundly boo'd as oddly flaw'd.)
