The bus was washed down Sasbrina's throat. "Okay... so she didn't see us. She drank us. Um... I suppose we can turn this into a lesson about human biology?" I turned and met the horrified stares of the many students (who we need more of!). "Okay... well we're currently in the esophagus. Not really being squeezed down by peristalsis since we're a bit on the small side... but you get the idea. Now, does anyone know what comes after the esophagus?" I turned to them again. They were still staring blankly, horrified expressions on their faces. "That's right, the stomach! Glad you're all on your toes..." The bus continued to travel down Sabrina's esophagus.
