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. 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, a habit 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. They found that they could erase the chalk marks J. J. Kilroy made and get paid double. When J.J. Kilroy decided to use a yellow crayon, which was harder to erase, the cheating stopped. 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. Kilroy Was Here was the name of a song by the band The Move on their self-titled debut album. From the lyrics: "Kilroy was here/Left his name around the place/Kilroy was here/Though I've never seen his face"

Well, he was here just now.....
