Wanda: (panicked) "Cosmo! Timmy's parents found Poof!"

Cosmo (also panicked) "Oh no! Those people have no idea how to raise a child! (notices Timmy glaring) No offense, Timmy."

Timmy: (deadpan) "None taken..."

"You know how your father once told you he was going to take you to Disneyworld, and then drove you to an abandoned parking lot and said, "Oh no, Disneyworld burned down"? Remember how you cried? Well, your dad did that because he loved you."

"All I wanted was for you to love me, to accept me. I thought it was my honor that I wanted, but really, I was trying to please you. You, my father who banished me just for talking out of turn! My father who challenged me, a thirteen year-old boy, to an Agni Kai! How can you possibly justify a duel with a child?"

"You WILL learn respect, and suffering will be your teacher."

Nuka: I'll do it for you, mother! (climbs onto a log dam)
Reaction: You know you're the disappointment child / a fuck-up when you do something suicidal and your mother doesn't even say; "Be careful".

"If my son talked like that, I'd beat him to within an inch of his life, I'd whip him senseless with my belt, and hold his head in the toilet till he was begging for mercy! I still don't see why the judge cut off my visitation rights.

"I haven't smiled once since the day you were born."

Green Goblin, to Harley Quinn: I've never seen someone be so cruel to someone they love!

Harry Osborn: Really, dad?

Green Goblin: SHUT UP OR YOU'RE OUT OF THE WILL!
