A few fraternity brothers needed to fill a science requirement in order to graduate, so they spent weeks studying for the final.
The day of the exam arrived, and they were more than ready for the test. The teacher pulled out a chart that had different pictures of birds’ legs.
The teacher said, “This is your exam. Name these birds by their legs.”
After ten minutes one boy stood up, absolutely furious, and slammed the paper down on the teacher’s desk.
“Unbelievable!” he yelled. “You knew I needed to pass this exam to graduate. How could you do this to me?”
The guy began to leave the room and the teacher yelled at him, “Hey you, what’s your name?”
The student pulled up his pants, revealing his legs, and said, “I don’t know, sir. You tell me.”
