it's too long to be a quote, but I never forgot this scene... (I still remember how he said "Teeny tiny baby coffins")
Young Mother: We're not vaccinating.
Young Mother: [Takes a toy frog and starts to make frog sounds]
House: Think they don't work?
Young Mother: I think some multinational pharmaceutical company wants me to think they work. Pad their bottom line.
House: Mmmm. May I? [He takes the frog and starts to do the gribbit noise with the baby]
Young Mother: [Whispered] Sure.
House: Gribbit, gribbit, gribbit. All natural no dies. That's a good business: all-natural children's toys. Those toy companies, they don't arbitrarily mark up their frogs. They don't lie about how much they spend in research and development. The worst a toy company can be accused of is making a really boring frog.
House: Gribbit, gribbit, gribbit. You know another really good business? Teeny tiny baby coffins. You can get them in frog green or fogo engine red. Really. The antibodies in yummy mummy only protect the kid for 6 months, which is why these companies think they can gouge you. They think that you'll spend whatever they ask to keep your kid alive. Want to change things? Prove them wrong. A few hundred parents like you decide they'd rather let their kid die then cough up 40 bucks for a vaccination, believe me, prices will drop REALLY fast. Gribbit, gribbit, gribbit, gribbit, gribbit.
