Kilziggyroy
During the 2007 NSS Convention in Marengo, Indiana, I asked Jerry to do this classic pose so I could photograph him. I put the picture on myspace and identified him as "Ziggy". Jerry pointed out that he wasn't Ziggy but Kilroy. "Right", I thought, "but who is Ziggy and who is Kilroy"?Well, Jerry pointed out that Kilroy was a cartoon drawn on a wall accompanied by the saying "Kilroy was here". I remembered that as being true but wondered why I had thought of it as Ziggy. Well, Ziggy looks just like Kilroy, it turns out. Ziggy is a small, bald, pantless, almost featureless character with a large nose.
Read and peruse for yourself and you will see how much they look alike.
My feeling about it? Ziggy and Kilroy are the same person. Have you actually ever seen them together? No, I think not. Maybe Ziggy posed as Kilroy. Or maybe Ziggy posed as Jerry pretending to be Kilroy. Or maybe Kilroy posed as Jerry disguised as Ziggy. Something to think about.......
KILROY
Kilroy was here is an American popular culture expression, often seen in graffiti. Its origins are open to speculation, but recognition of it and the distinctive doodle of "Kilroy" peeking over a wall is almost ubiquitous among U.S. residents who lived during World War II through the Korean War. 
The same doodle also appears in other cultures, but the character peeping over the wall is not named Kilroy but Foo, i.e. Foo was here. In the United Kingdom, such graffiti are known as "chads". In Chile, the graphic is known as a "sapo" [toad]; this may refer to the character's peeping, an activity associated with frogs because of their protruding eyes.

The phrase appears to have originated through United States servicemen, who would draw the doodle and the text "Kilroy Was Here" on the walls or elsewhere they were stationed, encamped, or visited. Brewer's Dictionary of Phrase and Fable notes that it was particularly associated with the Air Transport Command, at least when observed in the United Kingdom. One theory identifies James J. Kilroy, an American shipyard inspector, as the man behind the signature. During World War II he worked at the Bethlehem Steel Shipyard in Quincy, Massachusetts, where he claimed to have used the phrase to mark rivets he had checked. The builders, whose rivets J. J. Kilroy was counting, were paid depending on the number of rivets they put in. A riveter would make a chalk mark at the end of his or her shift to show where they had left off and the next riveter had started. Unscrupulous riveters discovered that, if they started work before the inspector arrived, they could receive extra pay by erasing the previous worker's chalk mark and chalking a mark farther back on the same seam, giving themselves credit for some of the previous riveter's work. J.J. Kilroy stopped this practice by writing "Kilroy was here" at the site of each chalk mark. At the time, ships were being sent out before they had been painted, so when sealed areas were opened for maintenance, soldiers found an unexplained name scrawled. Thousands of servicemen may have potentially seen his slogan on the outgoing ships and Kilroy's omnipresence and inscrutability sparked the legend. Afterwards, servicemen could have begun placing the slogan on different places and especially in new captured areas or landings. At some later point, the graffiti (Chad) and slogan (Kilroy was here) must have merged. (Michael Quinion. 3 April 1999.
Ziggy, on the other hand, is a daily single panel cartoon by Tom Wilson, an American Greetings executive. The character was originaly inspired by the comic "Zigfried Schlump" drawn by a college student with the pseudonym "clawmute" at the University of Akron, in Ohio. Craig Yoe (currently comic artist for Big Boy Restaurant), an employee of American Greetings at that time, collected some of these and showed them to Tom Wilson, who was inspired to recast the character as Ziggy.
Ziggy is a small, bald, pantless, almost featureless character (save for his large nose) who seems to have no job, hobbies, or romantic partner, just a menagerie of pets: Fuzz, a small white dog; Sid, a cat afraid of mice; Josh, a discouraging parrot; Goldie, a fish; and Wack, a duck. The appeal of the cast is juxtaposed with the endless stream of misfortunes which befall Ziggy.
