Do Fish Wear Pyjamas is a very enjoyable childrens book, set in a small Irish town. It follows two aliens who crash land in the town, and attempt to learn about earth's culture and the town's medieval history. The illustrations really capture the atmosphere of the book, which manages to both be very funny, and also contain a lot of interesting information about the locality the book is set in. The book was apparently written with input from local schoolchildren,and it shows, with parts alternating between being funny and scary. A book for any children who like an adventure, it's a very fun read.
