Imagine you’re a nervous student, a freshman in college, on your way to take your first big exam. As you walk across campus, your heart is racing, you’re trying to remember your notes. As you round the corner and head toward the testing center, you see what looks like a giant stack of french fries - bright yellow and ten feet tall. For a second, your mind is not on the exam. You might laugh or feel a bit lighter for just a moment.
