Can you improve your English by watching jokes?

I once bought an English joke booklet. My feelings are useful.

You must choose those shorter jokes. This looks effortless and casual, and you can also feel the humorous culture of Britain and America and learn some knowledge.

Like this:

A: My uncle has 1000 people.

He is really a big shot. What does he do?

C: the maintenance worker in the cemetery.

There are 1000 people under my uncle.

-He's really a big shot. What do you do?

Graveyard keeper.

This is a good example, you can not only smile, but also gain a spoken sentence. He is really important. To say that someone is someone means that he is a big shot.
