A fresh faced recent graduate of the Cosmos University goes into a TEFL Training School one day.

He stand next to an older guy, with real qualifications, at reception, points at a crocodile in the corner and asks "Does your crocodile bite?"

The guy says "No he doesn't"

The crocodile waddles from the corner and savages the TEFL Foetus's leg..

The Foetus says "I thought you said your crocodile doesn't bite !"

"That not my crocodile" came the reply.
