"And here we have the school cafeteria! Home to many delicious foods. The carrot sign is for vegans, the cheese is for vegetarians. The steak is for meat-eaters, not to be confused with the cow, which is for obligate carnivores. The geode is for people who eat rocks and minerals, the baguette with a line through it is gluten free, the banana is various fruits, and the cake is for desserts.

People with otherwise-baseline tastes have been known to enjoy their fried crickets. I am not one of those people, but I wouldn't want you to miss out if it turns out you are."
