A boy was at school and his teacher asked him to learn 3 new words over the weekend. His father is a pilot and taught him the word "takeoff." His mother is a zoo keeper and taught him the word "zebra." His big sister was going to have a baby and taught him the word "baby." He went to school the next day and his teacher asked, ''What are your three words?'' The boy said, ''Takeoff zebra baby.''
