Why didn’t the oven go to college?

Short answer: Because it didn't want to be baked into a "smart cookie"! 🍪😉

Explanation: This answer plays on the pun of the oven not wanting to become a "smart cookie" by going to college. It suggests that the oven is already "smart" in terms of its functionality, so it doesn't need to pursue higher education. The use of the cookie emoji adds a playful touch to the answer.
