Xmastime TV Worlds Colliding

Sheldon: If I've learned anything from British television shows on PBS it's that servants dine downstairs with their own kind.
Leonard: What?
Sheldon: It's a kindness, Leonard. Otherwise, you're cruelly tempting them with a glimpse of a world that's just beyond their soot stained fingertips.

Of course, it occurs to me that Sheldon and the Dowager would absolutely love each other.
