Chemically Imbalanced, Part 4

(I read the Chemically Imbalanced stories, and I decide to give it a go.)

Me: “Sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium sodium.”

Boyfriend: “What?”

Me: “You’re supposed to say Batman!”

Boyfriend: “What? Why?”

Me: “What is the chemical symbol for Sodium?”

Boyfriend: “Really? You thought I would make that connection? Well, fine then. Barium, Thulium, Muidos.”

(I frantically searching the internet trying to figure out what ‘Muidos’ is. I figure it’s a Spanish word or something.)

Me: “I have no clue what ‘muidos’ is. I got ‘BaTm,’ so is the last one Spanish for ‘an’?”

Boyfriend: “Sodium backwards.”

Me: “Sodium is ‘Na’, so… Oh my god! That totally made my life!”
