It is Friday, time for a joke.
A new prisoner entered the crowded jail cafeteria and sat down along with the other inmates waiting for lunch. Across the room one of the inmates stood up and yelled, #45. Everyone laughed. A moment later a different inmate on the opposite side of the room stood up and yelled, #32. Again, everyone laughed.
The new prisoner was confounded. He asked the guy next to him what was going on. The inmate explained that they had all been there so long, that they had numbered the many jokes they all knew. Instead of delivering them word for word, they just called out the number. It was a tradition they all enjoyed.
So the new prisoner, who wanted to fit in, stood up and called out, "#67". No one laughed, and the new prisoner sat down.
His mentor leaned over and said, "Some people can tell jokes, and some can't".
