They sit down for dinner. They eat in silence. Then one says something circumstantial. The other replies something circumstantial. They look at each other. They keep chewing as they look at each other. One of them chews so hard that a tooth comes off. She spits out the tooth and throws it in the plant pot. The plant inside the pot becomes alive and carnivorous. It eats them both and spits out all their teeth, one by one. It then takes a massive shit inside a bag and places it on the table for the next couple’s dinner. And so on until the end of humanity. The end.
