Buffy sat at the kitchen table; she was struggling with her checkbook. Then, Dawn walked behind her:
“Buffy, ‘The hardest thing in this world is to live in it.’”
“You know, Dawn, that was not the last thing I said before I jumped.”
“That's the last thing I heard.”
“Well, I said something else as I jumped into the Portal.”
“I didn't hear anything. What did you say, Buffy?”
Buffy didn't say anything, and Dawn stared at her.
“What did you say, Buffy?” Then, Dawn gasped. “You said it, didn't you.”
Buffy stood up and declaimed,
“To Infinity, And Beyond!”
“Buffy the Vampire Slayer” is the possession of Joss Whedon and Mutant Enemy. “Toy Story” is the possession of Pixar and its director and chief screenwriter, John Lasseter. No infringement is intended.
You might want to look up that movie's other writers, however.
