O is both the human mouth, and an ungoverned sound from deep within. Oh is the shallow, breathy exhalation of a Valley Girl with a new retainer.

O claims space/Oh collapses.

O is forceful, a stiff-arm/Oh is ineffectual, and flitters.

O is emotive/Oh so bland,unlike the quixotic ampersand.

[Write poem using both ampersand and Samarkand. Go!]

O stops time/Oh dribbles interminably.

Even as colloquialism, Oh has been irredeemably Simpsonized by D’oh.

On O’s resonance with the full moon, see the New Yorker cover.
