The pretty teacher was concerned with one of her young students so she took him aside after class one day. "Little Johnny, why has your school work been so poor lately?" "I'm in love," replied Little Johnny. Holding back an urge to smile, the teacher asked, "With whom?" "With you!" he said. "But Little Johnny," said the teacher gently, "don't you see how silly that is? Sure I'd like a husband of my own someday... but I don't want a child." "Oh, don't worry," said Little Johnny reassuringly, "I'll use a rubber!"
