Description: What grows six times in size?
During a human science class for younger students, the teacher asked
the students what part of the human body could grow to six times its size at
certain times. A little girl raised her hand and said, "Teacher, you know
my daddy's a preacher and you know we don't say those words in my house.
You are just trying to embarrass me." Next he called on Johnny and Johnny
said, "The iris, it grows to six times it size when you are in the dark."
Teacher said, "That's right Johnny." Then said, "Little girls you have a
very dirty mind, and when you grow up and get married one day, you are going
to be very disappointed."
