And now, a word from Sheldon

Now, you listen here. I have being telling you since you were four years old, it's okay to be smarter than everybody but you can't go around pointing it out. -Mary

Why not? -Sheldon

Because people don't like it. You don't remember all the ass kickings you got from the neighbor kids. Now lets get cracking. Shower, shirt, shoes and let's shove off.(Mary leaves the room) -Mary

There wouldn't have been any ass kickings if that stupid death ray had worked. -Sheldon
