EVE: Eve, maiden name. Both sad in Eden? I dash to be manned. I am Eve. ADAM: Madam I'm Adam. Named under a ban. A bared, nude man. Madam, I'm Adam. EVE: Tut-tut, mad Adam. Tut-tut.

Some word (not letter) palindromes

Does milk machinery milk does? Women understand men; few men understand women. bores are people that say that people are bores. So patient a doctor to try to doctor a patient so. (J. A. Lindon) God knows man. What is doubtful is what man knows God. You can cage a swallow, can't you, but you can't swallow a cage, can you? Girl, bathing on Bikini, eyeing boy, finds boy eyeing

bikini on bathing girl.

Amusing is that company of fond people bores people fond of

company that is amusing. (J. A. Lindon)

Word palindrome poem

Dies slowly fading day, winds mournful sigh,

Brightly stars are waking;

Flies owlet hooting, holding revel high,

Nightly silence breaking.

Breaking silence nightly,

High revel holding, hooting owlet flies;

Waking are stars brightly,

Sigh mournful winds, day fading slowly dies.

A. Cyril Pearson, Pictured Puzzles and Word Play, George Routledge and Sons, London, 1907, p. 314

Line palindrome poems

As I was passing near the jail I met a man, but hurried by. His face was ghastly, grimly pale. He had a gun. I wondered why He had. A gun? I wondered... why, His face was ghastly! Grimly pale, I met a man, but hurried by, As I was passing near the jail.

DOPPELGANGER (umlaut on the A)

Entering the lonely house with my wife,

I saw him for the first time

Peering furtively from behind a bush--

Blackness that moved,

A shape amid the shadows,

A momentary glimpse of gleaming eyes

Revealed in the ragged moon.

A closer look (he seemed to turn) might have Put him to flight forever--

I dared not

(For reasons that I failed to understand),

Though I knew I should act at once.

I puzzled over it, hiding alone, Watching the woman as she neared the gate.

He came, and I saw him crouching

Night after night. Night after night

He came, and I saw him crouching,

Watching the woman as she neared the gate.

I puzzled over it, hiding alone--

Though I knew I should act at once,

For reasons that I failed to understand

I dared not

Put him to flight forever.

A closer look (he seemed to turn) might have

Revealed in the ragged moon

A momentary glimpse of gleaming eyes,

A shape amid the shadows,

Blackness that moved.

Peering furtively from behind a bush,

I saw him, for the first time,

Entering the lonely house with my wife.
