An old man is in a restaurant. On the next table, he sees a punk with a red crest. He looks at him for a while. The punk, annoyed by this, gets up and goes to the old man:
- What’s the matter, grandpa ?! Have you ever done something crazy in your life ?!
The old man stares at him in the eyes and answers:
- Yes, exactly. One day I was so drunk that I f@cked a chicken so I wondered if you were not my son.
