Longest palindrome

Heard this from one of my lecturers while doing some programming exercise to check if a string is a palindrome:

rise to vote sir

Pretty impressive. Anyone know of a longer one?

A man, a plan, a canal - Panama!

Satan oscillate my metallic sonatas

A man, a plan, a cat, a ham, a yak, a yam, a hat, a canal--Panama!

nelli plaatst op 'n parterretrap 'n pot staalpillen

The second one is the most impressive, although they're both, frankly, ridiculous.

Hell, that's crazy.
What's even scarier is that someone actually sat there trying to figure out a way to make that into a palindrome 😕

according to the out-of-print book language on vacation, the author "contrived" a palindrome thus:
the french surname "delessert", while not common, does exist. it is logical to assume that at least one of these was an architect.
an alternate spelling of "trestle" is "tressel", and you can make that a verb. so, it is logical(?) to assume again that architect delessert may have tresseled some objects, but not others.
those would be described as delessert-nontresseled.
without viewing the web sites, i know that you can contrive a very long palindrome by starting with "dennis", ending with "sinned", and containing "and edna" in the very middle, with a whole bunch of names in between.
that book also covered anagrams, antigrams, and transposes.

If Adam and Eve spoke english (who wants to doubt that) 🙂 they must have spoken the first palindromes when they met.

- Madam, I'm Adam
- Eve

Straw? No, too stupid a fad. I put soot on warts.

It seems we are permitted to ignore punctuation, in which case a palindrome of any length can be achieved simply. Short example:

"E C I F F O S R O T C O D E H T T A M A X E E Y E S I H G N I R U D T O P E L B B O C D L E I F R E T S E H C D L A W S O D A I S," said Oswald Chesterfield Cobblepot during his eye exam at the doctor's office.

Obviously the device of having a speaker say a bunch of letters can get us a palindrome as long as we want, but it's not too clever. It's much better for palindromes to be clever, in my opinion. This one of mine is just stupid 🙂
Can anyone tell me the better-known alias of the fictional character Oswald Chesterfield Cobblepot?

The longest one I've ever seen is:

it sadly is in Suomi that I don't speek, but a friend of mine is finnish and said it was a story that made sence. I printed it out and it was nearly 12 pages.

Great scott! A palindrome that makes sense!? That's unearthly!

Obviou ...[text shortened]... anyone tell me the better-known alias of the fictional character Oswald Chesterfield Cobblepot?

Would Mr Cobblepot prefer to be known as the Penguin?
