The history (or herstory) of Humpty Dumpty is uncertain. (Many versions are listed here http://en.wikipedia.org/wiki/Humpty_Dumpty ) I do agree that the lesson for children is that some changes are irreversible. (Here is an adult comedy with profanity that addresses Humpty Dumpty's fate http://www.boreme.com/boreme/funny-2007/ricky-gervais-humpty-dumpty-p1.php)
So here is the original Humpty Dumpty nursery rhyme or lyrics:
Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again.
And here are the original lyrics my son wrote last summer (at aged 10):
Humpty Dumpty worked in a Mall.
Humpty Dumpty had a great fall.
All the Mall's lawyers and all the Mall's men
Had egg for breakfast again and again.
Now the new moral is the big establishments will eat you up!
