Big Bang Theory Quote
Sheldon: I think you're overestimating the tensile strength of the substructure you're building.
Howard: Sheldon, I know what I'm doing.
Sheldon: If you knew what you were doing, there wouldn't be a space toilet where my coffee table should be.
Raj: Howard, wait. Why don't you use this instead of the PVC to keep the transverse filter assembly in place?
Howard: Because this is not a spare part from the space station. This is the thing from the pizza box that keeps the lid from touching the cheese.
Raj: Is that what that's for? In India, the lid just touches the cheese.
(turning to Sheldon)
Raj: Of course, we also have rampant poverty and periodic outbreaks of cholera, so a little cardboard in our cheese is no biggie.
