The wacky fifth grader and the tall karate sensei walk into a froyo shop. The sensei orders a plain yogurt with no toppings. The fifth grader orders every topping they have.

The shop owner says, "That'll be $42.50."

The sensei looks at the fifth grader and says, "This is your first lesson in balance."

The fifth grader replies, "And this is your first lesson in chaos theory," then accidentally knocks over the sprinkle dispenser, creating a rainbow avalanche that somehow forms a perfect yin-yang symbol on the floor.​​​​​​​​​​​​​​​​
