«Moon Man» by Tomi Ungerer

In this classic story by one of the world's best-loved and acclaimed storytellers for children, the man in the moon looks down on the happy, dancing people on Earth every night, wishing he could join them. He hitches a ride on a passing comet, but quickly finds himself thrown into jail by people who see him as an invader, rather than a friendly visitor. The Moon Man, however, has a most unusual - but perfectly logical - means of escape, and sets out to make his way back home.
