They have an area of the school named 'No Dames Corner' where girls are not allowed. coming up with new schemes to bother the girls. The type of activities that the boy's will dream up is very dated. After all, this book was written over 60 yrs ago but never the less it is clean fun and a good glimpse into the early lives of baby boomers. Rupert and his friends create a UNIVAC computer at the fair and the answers the 'computer' types out are only the beginning to the fun the boys will have.
