Gintama

“A prison, you say? You think you'll be free if you go to the world above? A girl like you can never be free no matter where you go. After all, we humans are apes put in a cage called Earth. There is no difference between the world above and the world below. The only difference is which is bigger or smaller. People who pout about how confining the cage is can never be happy. They live their lives only seeing the iron bars. A true lack of freedom is when you cage your soul.”

“When you are down, how do you pick yourself up? People fall into two categories... depending on how they pick themselves up. The first one sees somebody who is worse off and thinks, "Hey! I am better off than that guy." And the second kind of guy sees a challenge and tries to raise himself to it.”

“Do you have any idea how stupid we are? Don't underestimate us!!!”
