You shouldn’t mess with graffiti writers. The longest recorded piece of graffiti was painted by a student in the toilets of his college at Changsha, China in 1915. It consisted of over 4000 characters criticising his teachers and the state of Chinese society.

After completing this masterpiece the student handed himself in and was paraded in front of the school and threatened with expulsion. The student as a 22 year old Chairman Mao. A graffiti artist who later founded the People’s Republic of China and was responsible for the deaths of over 30 million people.
