A sentence with a cocky tone?

Question

Answer 1

I saw a clip from House where he told his colleagues that he was going to "listen to you ideas, mock them all, and then embrace my own". He's quite cocky, that Dr. House. Even if he is a fictional character. *cough*

Answer 2

At airport customs:

"Sir, do you have anything to declare?"

"I have nothing to declare but my own genius."

I'd say that's pretty cocky.
