Are there any realistic humorous jokes?

Once upon a time, a man went to the bird market to buy birds. He found a parrot with a price of 3 yuan. He called the boss and asked, Is it just a sick parrot? Why is it so cheap? The boss said, who is it because this parrot can only say one sentence? The man thought I would teach him to talk, so he spent 3 yuan. The parrot bought it to teach him to talk. After teaching all night, he didn't learn anything else. He said, "Who will teach him after work?" "Who is it?" Who is the person who collects electricity? Who is the person who collects electricity? When the person who collects electricity came back from work, he found a man foaming at the door and said to himself, Who is this? The parrot said, who collects the electricity bill!
