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
legs 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!
