Leonard: Why can't he have a desk, Sheldon?
Sheldon: Oh, Lord, will this day never end? As I've explained repeatedly to Dr. Koothrappali, whose ability to comprehend the American idiom fails him when it's convenient, there's absolutely no money in my budget for additional office furniture.
Raj: Oh, but there's money for a drawer full of Red Vines, a marshmallow shooting rifle, and a super executive ant farm with glow-in-the-dark sand?
Sheldon: Yes.
