Confidence is ignorance. If you're feeling cocky, it's because there's something you don't know.

It's like learning to ride a unicorn. You never forget.

I never tell anyone exactly how clever I am. They would be too scared.

If I win, I'm a prodigy. If I lose, then I'm crazy. That's the way history is written.

If you were me, then I'd be you, and if I were you, then I'd hide somewhere far away.

Trust me. I'm a genius.

No matter what dimension you're in, there's a big-headed male trying to take over the world.

Listen to me, goblin. You're stupid, let's accept that and move on.

Good. Illegal is always faster.

Butler could kill you a hundred different ways without use of his armoury. Though I'm sure one would be quite sufficient.
