"End your sentences in "Woof" please."

"People need to live their life with a clear conscience. When you want to walk on a straight path, somehow you get yourself stained with mud. However, as long as we never give up, one day the mud on you will dry up and fall off."

— Gintoki Sakata · Gintama

"Do you really intend to lose even more of your friends for something like that? I'll pass on that. As long as I'm alive, I'll live by my own rules. I'll live as I see fit and protect that which I hold dear."

— Gintoki Sakata · Gintama

"Whether I go or not, I'll die anyway. I have an organ more important than my heart. Although you can't see it, I feel it going through my head down to my feet, and I know it exists within me. It lets me stand on my feet, it lets me walk forward without trembling. If I stop here, I feel like it would break... My soul will break."

— Gintoki Sakata · Gintama

"A samurai doesn't need a reason to do what's right. If you want to protect her, you must draw your sword."

— Gintoki Sakata · Gintama

"That's like what an evil organization in some anime would do."

— Gintoki Sakata · Gintama

"You STILL don't get it? When you tossed all of that away, a few important things were discarded as well. You abandoned your friends? More like you were afraid of BEING abandoned. You fight by yourself? More like you hid yourself in solitude from the beginning. You abandoned yourself? No... You just couldn't bear the pain of having a heavy load place upon you, or being a heavy load, so you ran. Like the coward you are. If you want to live your life abandoning one thing after another, that's your choice. But to try to incite your student to join you because you can't handle being alone, makes you a fool."

— Gintoki Sakata · Gintama
