Final answer:
Without specific context, it is not possible to accurately determine the differences between kids' pizza and Joe Schmo's pizza; however, potential differences could be in size, shape, flavor, and toppings.
Step-by-step explanation:
When considering the differences between kids' pizza and Joe Schmo's pizza, we can refer to criteria such as size, shape, flavor, toppings, crust, and cheese, although the actual differences may vary depending on the specific context or pizza establishment. However, for the purpose of answering the question, without additional context, we would not be able to determine the precise differences. Therefore, we can only speculate that potential differences might include size and shape intended for child-friendly portions or flavor and toppings that cater to common children's preferences.
