2.) Master Roshi
The Roshi is a bit of an eccentric character, and the only professor you have that starts every class with a dirty joke. You have definitely caught this guy ogling your female classmates on more than one occasion and they don’t much appreciate it. Don’t let him fool you though, behind the perverted exterior lies a wealth of knowledge. He may be a bit weird but if you stick his class out you are bound to learn something worth while.
