Howard: If I'm gonna have any chance of raising this kid, I need to come up with a big idea to make some money.
Leonard: There's no reason you can't.
Howard: That's easy for you to say. You and Sheldon already came up with your superfluid helium model.
Leonard: That's just research. We're never gonna make any money from it.
Sheldon: Forget helium. The real superfluid is the fruit punch in this mug. It reminds me of my daddy's secret "Don't Tell Mama" juice.
