Professor and sailor joke

A Professor was traveling by boat. On his way he asked the sailor: "Do you know Biology, Ecology, Zoology, Geography, physiology?"

The sailor said no to all his questions.

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

After a while the boat started sinking. The Sailor asked, "the Professor, do you know swiminology and escapology from sharkology?"

The professor said no.

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