The 10th grade teacher asks Jessica: What part of the human body increases to 10 times it’s normal size when excited?
Jessica responds: That’s disgusting! I don’t have to answer that question!
So the teacher asks little Johnny, who responds: That’s easy…the pupil of the eye. That’s correct, Johnny. Very good!
And turning to Jessica, she says: I’ve three things to say to you, young lady… first, you didn’t do your homework; second, you have a dirty mind; and third, you’re in for a big disappointment!
