J is a consonant letter, that the Romans could not tell from I. So, 'JESUS NAZARENUS REX JUDAEORUM' was 'IESVS NAZARENVS REX IVDÆORVM'. Some historians claim that this fact is a reason why the Roman Empire came to its end.
J is the international symbol for bukkake. Good bukkake gets a double ('JJ') stamp. Celebs involved in bukkake get a triple ('JJJ') stamp, but haven't been found yet.
- 'J-Lo' being the only exception ( having only one 'J' ). Reason being that a bukkake involving her is too common to be counted as special.
Jake and Joe are good examples of the letter J, however not as good as James, because anything involving that name is inherently awesome.
J in Popular Culture
The Australian 'alternative' FM radio station Triple J evolved from double J and has recently evolved into a mainstream alternative radio station that plays excellent quality alternative music such as Jet over and over again hoping to attract the new generation of stupid people who have no views of their own.
