A tourist was on a boat and he asks the boat guy:

.

do you know Biology, Psychology, Geography, Geology ?

.

The boat guy said:

.

NO to all the questions.

.

The tourist then said:

.

.

After a while, the boat started sinking, so the boatman asked the tourist :

.

Do you know Swimology and Escapology from Crocodilogy ?

.

The tourist said: NO !!

The boat guy replied:

.
