Prompt - wise

Seth wrote words on a piece of paper.

"No." He scratched it out. Scribbled some more.

"Stupid!" Scratched out again.

"I need to get Summer a ridonkulously amazing Chrismukkah present."

He suddenly looked over at Captain Oats.

"No, no. Last time you gave me advice I handed her a 'Jamaican me crazy' shirt and she practically strangled me with it!"

Seth returned to writing for a moment before looking back to the horse.

"Captain Oats, you're so wise. Like a miniature Buddha, covered in plastic."

The horse was still.

"Summer will love that box set of Yakuza Prep films! Thanks!"

Extra Chrismukkah points if you tell me what movie I swiped a quote from.
