"Harder Than Steel" joke

What part of the human body," asked the anatomy professor, "is harder than steel?" Nobody in the class volunteered the information, so he looked in the direction of a sweet coed and asked, "Can you tell me, Miss Riley?"
She blushed a deep scarlet and lowered her eyes, murmuring, "Oh, please don't ask me to answer that, professor!"
Crisply, he said, "The answer is the tissue of the nails. And you, Miss Riley," he added with a sigh, "are an optimist."
