“The exact origin of the phrase is unknown, but etymologists suspect it is a childish corruption of the German “Alle, alle auch sind frei!”, (literally, “Everyone, everyone also is free!”), which is purported to have been a cruel joke often played upon Holocaust victims by their jailers. At any particular time, a prisoner might be released, immediately upon which the phrase would be shouted. Any other prisoners who also left would be killed further down the road by Nazi soldiers.”

Wow. I thought it was so innocent.
