Joke: "SMS"

Dad just called and asked anxiously, "Are you okay?"

I said, "Good! What's the matter?"

He said: "I received a text message saying that you have been kidnapped, I should call him in three days 200,000 yuan, or I will kill!"

I was busy comforting dad: "Don't worry, I'm fine, that's a liar!" When did you receive the text message?"

He hesitated and said, "Last month, as soon as I got busy, I forgot about it..." .
