A professor was traveling on a boat. On his way he asked a sailor:

"Do you know Biology, Ecology, Zoology, Geography and Physiology"

The sailor said no to all his questions.

Professor: "What the hell do you know on the earth, you will die of illiteracy"

After a while the boat started sinking. The sailor asked the professor

"Do you know swimology and escapology from sharkology?"

The professor said no

Sailor: "Well, sharkology and crocodilogy will eat your asshology, headology and you will dieology because of your mouthology"
