Sex education
A fifth grade teacher is told she must teach sex education to her class. She decides to use a math technique to teach the subject, and thinks flash cards will work well.
The next day in class, she holds up the first flash card, a picture of a breast, and asked "Does anyone know what this is?" Little Suzie responds-"I know, I know! It's a picture of a breast and my mommy has two of them!" The teacher says "very good Suzie, you get a star for the exercise"
The teacher grabs the next card and holds it up. It's a picture of a penis. She asks "Does anyone know what this is?" and little Tommy says, "I know I know! It a penis and my daddy has two of them!!!" The teacher says "well Tommy, It is a penis but your daddy can't have two of them."
Tommy says, "sure he does, he's got a little one he pees out of and a great big one he brushes mommy's teeth with!"
