Monday morning in biology class and the professor was asking questions about the weekends reading assignment. Who can tell me what part of the human body expands to 10 times its normal size when excited or stimulated?

He called on Stelle, an attractive coed who promptly blushed, saying, I refuse to answer that question on account that I am a _lady_.

The professor then called on the class valedictorian who said, That part of the body is the eye, maam.

The professor then said, Stelle, I can tell two things by your answer. One, you didnt read your assignment. And two, youre going to be sorely disappointed on your wedding night!
