Let's sing !

It's twelve o'clock Dickety tackety tack. I just saw a cat. Dickety tackety toe. It's twelve o'clock, you know. Dickety tackety tack. I just heard a snap. Dickety tackety toe. He caught a mouse, you know.

滴答，滴答，滴答。我刚才看见了一只猫。 滴答，滴答，滴答。十二点钟了，你知道的。 滴答，滴答，滴答。我刚才听到了啪嗒声。 滴答，滴答，滴答。他抓住了一只老鼠，你知道的！
