But I guess in war PC isn't really paid any regard is it. I do find this stuff hilarious though, mostly the innocence/ignorance of it all.
How To Spot A Jap is a section of a handbook distributed by the US War Dept in 1942 to their soldiers. I especially love the line on page 71 on how to trick a "Jap" with language - "or try Lalapalooza on them - that's a panic!" hehehe oh dear. They removed the "Jap" section from the handbook in 1944. Have a read and cringe.
