If you’ve spent at least one of the last three years in America alive, you’ve probably noticed some different variation of pumpkin product. Pumpkin spice chicken sausage, Pumpkin Spice Eggo Waffles, Thomas’ Pumpkin Spice Bagels, and most tragic of all—Philadephia Pumpkin Spice Cream Cheese. Since when did pumpkin leggo our eggos? What is the relationship between the New England pumpkin and the New York bagel? Who ever thought that cream cheese should integrate with pumpkin? When did the mania begin, and when will it end?

Some of the causes may be seasonal (“Want to taste autumn? Eat Pumpkin Eggos”), others based on hysterical scientific claims, while still others trend for ridiculously adorable reasons. Here’s a quick look at vegetable and pseudo-vegetable viral history—some of it based in real scientific fact, others grounded in outright nutritional hysteria.
