Unfortunately, Rusty Staub's kid book did not include the drug-, booze- and babe-fueled Mets of 1986. And to quote everyone's who's seen it, it's a choking hazard in September.
Out of curiosity, I looked up what other Mr. Met books are out there. The results are a little disconcerting.
Hopefully the last book is merely a rumor - Mr. Met's the last Opening Day starter not on the DL.
