That one has an interesting joke.

There was a blacksmith who was an apprentice.

A few years later, when I realized my skills, I stopped providing wine and meat to blacksmiths.

The blacksmith felt it.

One day, the blacksmith said, I am an apprentice, and I have another trick to teach you.

Just listen, and then drink meat!

A few years later, the blacksmith was still alive.

Teacher: Master, teach me the unique skills and don't be buried with you!

The blacksmith said: I am an apprentice! You must remember not to touch the red-hot iron with your hands!
