One day, a little boy went to a store with his mom. He saw a bag of candy and asked his mom to buy it for him. His mom said, “You can have it if you can answer a question.”

“What’s the question?” the little boy asked eagerly.

His mom said, “What do you call a cow that plays an instrument?”

The little boy thought for a moment and then confidently answered, “I don’t know, what do you call it?”

“Musical moo-sician!” his mom said.

The little boy laughed and enjoyed his candy, all thanks to his mom’s playful sense of humor.<|end_of_text|>
