Mr. Gumpy's Outing
By John Burningham; illustrated by the author
On a perfect summer day, Mr. Gumpy decides to take a ride on the river in his small boat. First he adds a boy and girl, and then an array of animals until the goat's kick causes a cumulative effect and everyone lands in the water. The book ends with a tea party for all.
