Little Johnny and Sex Education

A unit in sex education was about to begin, and each student had to bring in a permission slip in order to take it. Little Johnny handed in his slip and explained to the teacher, "My mom says I can take the course as long as there's no homework."

Give Me A Sentence Starting With I

Teacher: Johnny, give me a sentence starting with "I".
Little Johnny: I is...
Teacher: No, Little Johnny. Always say "I am."
Little Johnny: All right. "I am the ninth letter of the alphabet."

Little Johnny's Train

One day a teacher told her students to draw a train on a railway track for homework. The next day when the teacher started checking everybody's book, she came up to Little Johnny. "Show me the homework," she demanded. Little Johnny showed the teacher his notebook with only a picture of railroad tracks. The teacher asked, "Where is the train?" Little Johnny then replied, "You came late so the train went away."
