A young college student had stayed up all night studying for his
zoology test the next day.

As he entered the classroom, he saw ten
stands with ten birds on them.

Each bird had a sack over its head;
only the legs were showing.

He sat straight in the front row because
he wanted to do the best job possible.

The professor announced that
the test would be to look at each of the birds' legs and give the
common name, habitat, genus and species.

The student looked at each of the birds' legs.

They all looked the
same to him.

He began to get upset.

He had stayed up all night
studying and now had to identify birds by their legs.

The more he
thought about it the madder he got.

Finally he could stand it no longer.

He went up to the professor's
desk and said, "What a stupid test! How could anyone tell the
difference between birds by looking at their legs?"

With that the
student threw his test on the professor's desk and walked to the
door.

The professor was surprised.

The class was so big that he didn't
know every student's name so as the student reached the door the
professor called, "Mister, what's your name?"

The enraged student pulled up his pant legs and said, "You tell me
buddy! You tell me!"
