The Venture Bros., Season 2

Insect King:
No! Not the ring of power! It's the only thing that can steal my black heart.

Dean Venture:
Eat it!

[Dean begins randomly stabbing the Insect King]

Insect King:
Ow-eeee that f***ing hurts! Ow! Right down to the thorax, Dick! But it missed my Black heart.

Dean Venture:
Die!

[Dean severes the Insect King's arm and leg]

Insect King:
Ow, dude stop already, you're not even aiming for my black heart!

Dean Venture:
I vanquish you!

Insect King:
Come on, those are reproductive organs! Will you take the f***ing hint and stab me in the heart already?!

Dean Venture:
I got it! Your evil black heart is where your power comes from!

Insect King (feigning chagrin):
Oh no, you have learned my terrible secret!
