Sheldon: Okay. I'll say an element, and uh, you say an element whose name starts with the last letter of the one I said, okay? I'll start. Helium. Now, you could say Mercury. That would give me a Y. Ooh, very clever, that's a tough one. So I go Ytterbium, which gets you back to M. So you go Molybdenum, and I say Magnesium, you say Manganese, and I say Europium, and, and you're left with Mendelevium, and there are no more M's because I believe that Meitnerium should still be called Ekairidium, so congratulations, you win. Do you wanna go again?
