Mr. Czerwinski 

A teacher who assigned a whole had damn lot of assignments, but is so awesome that he forgets to collect the majority of them. He is also very lenient with bad answers and when he is in a good mood, he is actually a fun teacher.

"Well then your science teacher better be a Mr. Czerwinski, or you're screwed."
