Please tell me two jokes. If you have heard them, please tell me. It’s urgent~~

The first one is: one person tells a story to another person, saying: There once was a fool. He would only say no. When others asked him if he had eaten, he said no. When others asked him, what was his name? , he said no. Then the person asked another person, have you heard this story, and he said: No

The second one is this: One person said to another person: You are a pig. Another person said: I am a pig. After that, the man kept calling him a pig. One day, the man shouted on the stairs: I am not a pig.

Are they these two? .
