Any jokes?

A person always felt a little pain in his stomach recently, so he went to the hospital for examination one day. When he came to the hospital, the doctor told him to have a urine test. He took a small bowl to the bathroom and spent a lot of time trying to squeeze out a little. Just as he walked out of the bathroom, he tried to bump into a lady, who also came out of the bathroom for a urine test. The man's urine was hit, and he said angrily to the lady, "How can I test if you hit my urine?" The lady looked at him and said, "How stingy! I'll pay you a little." The man thought so, so the lady poured some from her small bowl for the man, and the man took the test sample and gave it to the laboratory. When taking the test paper three days later, the doctor said to the man, "You are pregnant." The man picked up the test paper without saying a word and ran home. When he entered the door, he said to his wife, "Look, you didn't listen to me when I said I was on it. You must be pregnant. "
