Final answer:
Julie Marie's joke asks what has four feet but cannot run, and the main answer is a table or chair as they are inanimate objects with four legs that cannot move on their own.
Step-by-step explanation:
The answer to Julie Marie's joke, “What stands on four feet but cannot run?”, could refer to a table or a chair. These objects typically have four “feet” or legs and maintain a stationary position. Despite standing on four feet, unlike animals or humans, a table or chair lacks the ability to run or move on its own.
