TV Quote of the Day (‘The Big Bang Theory,’ on Sheldon and ‘The Toad of Truth’)

Howard Wolowitz (played by Simon Helberg): “Sheldon, what the hell are you doing?”

Dr. Sheldon Cooper (played by Jim Parsons): “The same thing I’ve been doing for three days. Trying to figure out why electrons behave as if they have no mass when travelling through a graphene sheet.”

Bernadette Rostenkowski (played by Melissa Rauch): “With marbles?”

Sheldon: “Well, I needed something bigger than peas, now, didn’t I?”

Bernadette: “Sheldon, when was the last time you got any sleep?”

Sheldon: “I don’t know, two, three days. Not important. I don’t need sleep, I need answers. I need to determine where in this swamp of unbalanced formulas squatteth the toad of truth.”

Penny (played by Kaley Cuoco-Sweeting): “Toad of truth? Is that a physics thing?”
