I believe it began with the introduction of the Indiana Jones Esque ArcOfTheChocolate?, which of course when its power was unleashed turned all of the Nazis into Chocolate.
Quotes included:
"They'd be hollow of course" ... "And then you could headbutt a hole in them and eat them"
"Nazis for breakfast?"
"If they were very thin you could touch them and they'd turn into Cocoa Powder" ... "And then you could make Nazi hot chocolate!"
