Human Inefficiency

PA System: Good morning Barons!

Student1: Whatever....

(PA System continues on...then announcer starts squeaking with laughter.)

Class and teacher: ::sigh::

(Squeaking and hysterical laughter continue)

Class: Isn't someone going to shut her up? Why do we all have to suffer?!

Teacher: This is an example of the inefficiency of human beings.

Student2: Does that mean you're a robot?

Student3: At least her utility seems to be maximized...
