Many other people have criticized Yes, It's Hot in Here because A.J. Mass is too cynical and because it comes off as him complaining about how poorly the Mets treated him. While Mass does come off as disgruntled, most of the time it works in this book. Being a mascot is not all fun and games (as the title suggests). I rather enjoyed the behind the curtain reveals into how the Mets treated Mass. To me, this speaks volumes about how the organization is run as a whole.
Mass provides a lot of interesting information about mascots, including several humorous anecdotes about what a mascot experiences on a daily basis. From this book, I do have a greater appreciation for mascots, and there certainly is a difference between a great mascot and just some guy in a costume.
Yes, It's Hot in Here sometimes got a bit off track with Mass's personal vendettas, whether against the Mets or the San Diego Chicken, but most of the time Mass's sardonic and oftentimes ridiculing tone is what made this book enjoyable for me. If this book simply provided whimsical anecdotes of being a mascot, there would be nothing here. Mass does a great job of expressing his sheer joy in the world of mascots as well. Overall, Mass strikes a nice balance, providing the reader with just about everything they could want from a book about mascots.
