A science class was taking a test. The test was basically identifying birds by their feet. One student looked at the test and saw row after row of nothing but bird feet.
"That's it! I'm outta here!" he said. He handed his blank test in to the professor.
"What's your name young man?!" asked the professor angrily.
The student rolled up his pants, showing his feet.
"I don't know. You tell me."
