Raj: Please, Sheldon, I'm a young, virile visitor from a foreign land and I need to strut my stuff.
Sheldon: Let me offer you a compromise. Sometimes when I feel stifled and want a change of scenery, I use my imagination.
Raj: Oh, boy.
Sheldon: One of my favorite places to visit is the two-dimensional world described in Edwin Abbott's mathematical fantasy, Flatland.
Raj: I don't want to go to Flatland.
Sheldon: You're only saying that because you haven't been there. I am now a hexagon in two-dimensional space and can only perceive the edges of other objects.
Sheldon: Is that you, Raj? I don't recognize your edge.
