Not the best, but not the worst either
Format: Hardcover
By any means not the funniest book in the series, only the one on Krusty the Clown was more un-funny; but still a worthy addition to your collection and, just like all the others from the series providing a retrospective of anecdotes you might have forgotten.

Not that great
Huge "The Simpsons" fan. I watched all the episodes and read a lot of the comics and enjoy most. This one however was quite boring. Turns out I'm just not a big fan of Chief Wiggum. I really enjoyed The "Homer" and "Bart" book. But not this one. Maybe if you love Wiggum you'll love it. If you're not too fond of him then I wouldn't buy it.

Good for my collection.
Format: Hardcover
This was another quick and entertaining read. This instalment wasn't as enjoyable as some of the other books but it was still good. I'm glad to have it in my collection.
