Who was Kilroy ?

HEREis a site that gives some history.

Deeptread's drawing above is what we in Britain called Mr Chad, who - like Kilroy - appeared during World War II. Perhaps because we were more short of essentials than the USA was, he was always asking about something that was lacking, using the phrase "Wot - no ...?" For example, "Wot - no butter?"
Our guy wasn't just 'there', he was constantly whingeing about something! (Typical Brit...let me say it before some American cousin does!)

The feller pictured was known by Americans as "Luke the Spook".

I think Kilroy was an inspector and left his Kilroy was here to let them know he did his job!
