I, Me
Your ego... it's totally out of control. I mean, my ego isn't out of control. I'm the greatest. That's me. But your ego? Ugh, so out of control unlike my amazing ego.
Just keep going with this sentence about the ego. You can't stop, because really it's your ego that's out of control. That's I when you're saying it.

われ, わ

I am the greatest in the world! I am no baby like you, that's why. A baby who says "ga (が) ga ga ga!"
You're just destroying the ego of that other guy. "Why?" you ask? "Because I am the boss here. And you are the baby. Ego things."
