Everyone knows there is a lot of variety in the sorts of professors one gets throughout their college courses. What if every type was a character from Spongebob Squarepants?

1. The Cheerful Professor - Spongebob

He’s always super excited to teach, and wants to make sure his students enjoy his class as much as he possibly can.

2. The Clueless Professor - Patrick

He doesn’t even know what class he’s teaching, but hey, at least he found the classroom.

3. The Annoyed Professor - Squidward

Always annoyed, his students ponder whether he’s just a plain old jerk or he’s having personal troubles.

4. The Greedy Professor - Mr. Krabs

As long as you turn in something, you’re bound to get an A in his class. He’s just there to make sure he can collect a fat paycheck.

5. The Foreign Professor - Gary

You aren’t sure whether or not he’s a good professor, because you can only understand around 20% of what he’s saying. Hopefully his email correspondence is more intelligible.

6. The Jealous Professor - Plankton

Always upset he isn’t the professor everyone’s talking about, he tries desperately to win over his students but somehow fails miserably every time.

7. The Genius Professor - Sandy

She moonlights as a professor because she wants to share her wide range of insight on the topic, and often leaves her students confused yet amazed at what she’s teaching.

8. The “Sick” Professor - Fred the Fish

Every other class gets cancelled. You aren’t sure whether to be happy he cancelled class, or upset that this is the education you’re paying for.

9. The Hot Professor - Larry the Lobster

Everyone wants to take his class, but only because they want to spend every minute of class observing his perfect physique.

10. The Wholesome Professor - Mrs. Puff

She always shows up on time, always grades the homework on time, and makes sure her class is running like clockwork. She’s mastered teaching, and her students hate her for it.
