Was Humpty Dumpty An Egg?

I WAS BROWSING YAHOO! ANSWERS pages when I stumbled a question "Where in the nursery rhyme does it say humpty dumpty is an egg?" posted a couple of months ago by asker "I_is_a_patriot_1776". Curiousity got me searching for answers which I find interesting.

Humpty DumptyWikipedia has several lyric / text versions. Indeed, these do not explicitly state that Humpty Dumpty was an egg.

Common version:
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.
A riddle first published in 1810:
Humpty Dumpty sat on a wall,
Humpty Dumpty had a great fall;
Threescore men and threescore more,
Cannot place Humpty Dumpty as he was before.
A spoof for the Oxford Magazine in 1956:
In Sixteen Hundred and Forty-Eight
When England suffered the pains of state
The Roundheads lay siege to Colchester town
Where the king's men still fought for the crown

There One-Eyed Thompson stood on the wall
A gunner of deadliest aim of all
From St. Mary's Tower his cannon he fired
Humpty-Dumpty was its name

Humpty Dumpty sat on the wall,
Humpty Dumpty had a great fall;
All the king’s horses and all the king’s men
Couldn’t put Humpty together again.
There's a lot of speculations about who or what Humpty Dumpty is but here is the best answer from lpljr at Yahoo! Answers.
Humpty Dumpty was a slang in the eighteenth-century for short clumsy person. Humpty Dumpty was also the name of a canon in the sixteenth-century English civil war. He was mounted on a wall and was knocked down by enemy canon fire to the wall he was perched on. The king ordered him put back on the wall using men and horses but they failed to do so because Humpty was to enormous and heavy resulting in the king having to surrender and losing the war.
Now we know. Just sharing light stuff on a warm weekend. =)
