What's an Aes lyric that you think most people here don't understand? (But you get it)

So you think that you get something he said and most of the other Aes heads here don't understand? Let's see if you're right. I hope to learn something new.

The idea came to me just now listening to The Gates: "I go marching in I'm all O. E. O. " In the original wizard of Oz the guards at the witches castle are marching in and chanting "O. E. O... O-E-O" I know that scene because of an inside joke, I wonder if it's common knowledge.

Please tell me a lyric only you get
