Dr Xargle's Book of Earth Families

'Today we are going to learn about Earth families. An Earth family is a collection of Earthlings who belong to each other whether they like it or not.'Dr Xargle, the great, green alien school teacher is now attempting the hot topic of Earth relations, and his views are as refreshing, remarkable, and idiosyncratic as ever! Brother Earthlets are 'Bother Earthlets', smelly, sticky and dangerous, while Sister Earthlets, 'Sulker Earthlets', are shy, sneaky and give piercing shrieks. It's Earth, folks, and oh, how we know it!
