What are the cold jokes that you will never forget?

I saw the following facts with my own eyes.

1, I met a robber just now, and I said to him, "I'll give you money, so don't rob me."

He took the money and left.

2. "Grandpa, is it convenient?"

Hearing the sound, the uncle who looked at the toilet looked up and saw that a beggar had stretched out his bowl.

Grandpa thought for a moment and asked, "Would you like to have a meal?"
