Oops, that's palindrome, unless you are entering the new decade ass backwards, in which case YOU are the Palindrone.
Oddly enough, coinage of the term palindrome, meaning a phrase that reads the same going forwards or rearing backwards, involved no reference to Sarah Palin, although uncanny prophecy might be suspected. It derives from the Greek roots palin, meaning 'again' (and again and again -- insert own joke here), and dromos, meaning 'direction'. The classic Republican palindrome of the 20th century was "A man, a plan, a canal, Panama" in reference to Teddy Roosevelt. Connecting the Atlantic and Pacific oceans involved traveling in the wrong direction, whether coming or going, or something like that.
A classic Hebrew palindrome was "We explained the glutton who is in the honey was burned and incinerated" (פרשנו רעבתן שבדבש נתבער ונשרף ), which certainly proves that Jews have progressed in our sense of humor. (It's important to read a Hebrew palindrome from right to left, because otherwise its reversibility will be doubly negated.)
The Finnish word saippuakuppinippukauppias, meaning "soap dish vendor" is a palindrome, but apparently the Finns do not consider this funny.
Many palindromes encode useful or philisophical wisdom. For example, relying on Wikepedia as my source, we have:
Go hang a salami I'm a lasagna hog
Satan, oscillate my metallic sonatas
Mr. Owl ate my metal worm.
or the antiquarian:
Lisa Bonet ate no basil
For some reason probably related to their penchant for retrograde thinking, palindromes have appelaed to ideologues of the far right. The reactionary philologist Revilo P. Oliver had a name which was itself a palindrome, proving that his parents were such wingnuts, they would name a kid "Revilo" just to make a backward intellectual point. Obviously fans of William F. Buckley. It leads me to coin my own palindrome:
Revilo P. Oliver. LOL LOL LOL! Revilo P. Oliver.
Date palindromes like today are exceedingly rare, although they cluster around millennial changes. Using two-digit year abbreviations, one happened on 30/11/03 and another will happen nine days from now on 01/11/10.
Using four-digit year numerals, another will not occur for precisely a heck of a long time from now. Unless, of course, you're a backwards-thinking Palindrone, in which case you can revisit today at any time you please.
Feel free to add your own favorite palindrome, because you won't get a chance like this again to think in reverse, or vice versa.
UPDATE: See the comment below by VA Classical Liberal for a video clip of Weird Al Yankovic singing the song Bob, with more palindromes than you can count. My favorite: "Do geese see God?" Thanks!
