lol!
Actually, the term Tarheel for North Carolinians comes from the Revolutionary war. The legend says that when the British came to battle, the North Carlolinian soldiers stood steadfast and corageous as if they had tar on their heels.

Another legend is that the school mascot is Tarheel because Hinton James, the University's very first student, walked all the way to the campus from his home on the coast and when he arrived, had road tar on his feet. But he was so determined to come to the University of North Carolina at Chapel Hill, he walked the distance anyway.

Either way, no indians or animals were harmed in this experiment
