You shoot an arrow at the mouth of the sun so that it will grant you a gift of wisdom. You heard about a Greek hero doing this and the god in the sun gave him the wisdom to see everything. You're hoping it will work for you too.
You're standing around waiting for the wisdom to hit you when something else does. In the head. Ouch! You look down and it's a wheel of cheese (ち)! At first you're angry, until you realize that this must be a sign. Cheese IS wisdom. And the key to wisdom is eating a lot of cheese!
