Let's begin with his childhood notorious acts.
While SRK was four, he used to throw stones at his neighbor's house. Once he broke a child's teeth staying there. Later that night, the child's father, drunk, knocked at SRK's house. Khan's father opened the door and the man threatened to kill SRK. Father crosschecked with Shah Rukh as to whether or not he had committed the act of mischief. When he confessed, his dad asked him to go out and explain himself to the man who was not only drunk but also armed. Shah Rukh went outside and apologised for his deed.
