How is this clean joke on Phd.?

Question

This guy was very keen on doing Ph.D. and was in search of a subject on which no one did any research before! As he was thinking over it and finally found a cockroach on the table in front. Inspired he decided instantly to do a research on the roach.

He picked the cockroach and put it in the centre of the table and said "Run" - The cockroach ran.

He pulled out one leg of the cockroach, put it again in the centre of the table and said "Run" - The cockroach ran.

He pulled one more leg of the cockroach, put it again in the centre of the table and said "Run" - The cockroach ran.

This way the cockroach tried to run even when it had just one leg.

He pulled last leg of the cockroach, put it again in the centre of the table and said "Run" - The cockroach could not!

Satisfied with the study he started writing thesis

“When you pull out all the legs of a cockraoch, it cannot HEAR anymore.”
