The Mr. Men have been tickling children for generations with their funny and charming antics. The Mr Men for Grown-Ups series now gives adults the chance to laugh along as the Mr Men and Little Miss try to cope with the very grown-up world around them. Featuring Roger Hargreaves classic artwork alongside hilariously funny new text.

Mr Happy is usually a very happy fellow. But the morning after the office party, he doesn't feel so happy. In fact, he loses his smile. It couldn’t be that bad, could it?

The perfect book for anyone who has ever been to a work party and lived to tell the tale.
