Teenage Mutant Ninja Turtles, Season 1

Raph:
Who does Leo think he is? So what if I got a temper? I’m still the best fighter we’ve got. In fact, if anything, my anger makes me a better fighter. You understand me, don't you, Spike? Chew on your leaf if you understand me. [Spike chews on leaf] Yeah, I thought so.

Splinter:
[suddenly walks in] I understand you too.

Raph:
[scared out of his wits] Seriously, you gotta knock or something!

Splinter:
Raphael, let me tell you a story.

Raph:
[tiredly] Sensei, I'm not really in the mood for a story.

Splinter:
Spike, chew on your leaf if you're in the mood for a story. [Spike chews on his leaf] Very well. When I was a young man, I fell in love with a woman.

Raph:
[sarcastically; pretending to check the time] Oh, hey, is it that late already? [tries to leave]

Splinter:
[firmly] Sit! [Raph sits down in defeat and he continues] Her name was Tang Shen, and I was not the only one who loved her. There was another man competing for her attention, Oroku Saki.

Raph:
Shredder.

Splinter:
One day, he insulted me in front of her. He called me many things. I felt I couldn't let those insults go unanswered. I lost my temper, and over time, our rivalry festered into hatred. Until Shredder sought to finish me. And I lost my beloved Tang Shen.

Raph:
[lost for words; unsure of how to react] But... But it wasn't your fault. Shredder insulted you, you... You had no choice.

Splinter:
[through gritted teeth] "No choice"? I could have chosen to ignore him, I could have chosen to let his words wash over me, like a river over stone. [shamefully] But I let him anger me, it was I who made his words into weapons. That's the choice I made. What choice will you make?
