Rating: WORTHY!
Yes, it's that Jimmy Kimmel. And this isn't too bad of an effort. There's no educational content in it, but I think the book is fun and would be entertaining. The drawings - mostly back and white line drawings with some color - aren't bad at all.
The idea is that this goose is way serious and won't even hint at a smile. After a few pages there's a mirror included on the page for your kid to practice making faces aimed at cracking up the goose. Will it work? I think you know the foregone conclusion, although it's in hardback version and it ain't exactly cheap, but at around $9 as of this review, it's not too bad either. A used version would be cheaper still, and I commend this as an amusing read.
