I bought Kai a red ballon, and it was in the car.
As we were walking back to the car after school, the conversation went like this:
Me: Hey Kai, guess what? I've got a surprise for you!
Kai: Oh, oh! Can I close my eyes?
Me: Of course!
Kai (Excitedly): What is it mummy? Is it a stinky shoe? I love stinky shoes!
