"7 Times Original Size" joke
Reviewing homework assignments, the teacher asks Sandy to tell the class what part of the human body enlarges to seven times its original size when stimulated.
Sandy stands up and says, "Miss Smith, I know the answer, but I'm too embarrassed to say it."
"Paul," the teacher says, "Please tell the class what part of the human body enlarges to seven times its size when stimulated."
Paul stands and says, "When stimulated by light, the pupil of the eye enlarges to seven times its original size."
"Correct, Paul." Then, turning to Sandy, the teacher says, "First of all Sandy, you did not do your homework. Second, you have a very dirty mind. Third, when you marry, you're in for a very big disappointment!"
