Unlike various Roman emperors (post Augustus), he has never done any of the following, at least as far as we know so far:

Appointed his horse to the senate.
Murdered his mother and/or brother.
Married, impregnated, and then killed his sister.
Declared himself the reincarnation of Hercules, and insisted on being portrayed wearing a lion's skin and carrying a club.
Entered professional chariot races and/or other athletic competitions (and won every time, because anyone who beat him would be murdered)
Entered singing and musical performance contests, same rules, same results.
Paraded around the capital in heavy make-up and women's clothes, and worked nights as a high-class male prostitute.
Ordered the wives of senators to report to him for sex.
Ordered members of the senate who disagreed with him to commit suicide (usually by falling on their swords -- but opening one's veins was also acceptable).
Built himself a palace which took up a full 25% or more of the capital city, with a sprinkler system containing perfume.

Gee, what a great guy.
