HYPERS! I'm not sure, but this may just be one of the worst things I've seen thus far in my Scary Things Kids (& Adults) Do series of blogs.
When I saw this listing at eBay I laughed and shook my head. Some little monster took a sharpie or marker and wrote all over the inside of the dust jacket as you can see it shows above and then below. You can buy it now for $4.99 in all its glory.
Looks like they wrote all the names of their buddies down like Mike, Bill, and Phil--rhyming buddies perhaps. They even knew John Hancock! WOW. And of course Kathy and Tom. And maybe Dan with the smiley face inside the D. My bet is Kathy is the culprit since it's the only girls' name here and she was listing her boyfriends she was stalking around the playground.
Just for good measure, she added more names to the endpapers in case the dust jacket didn't cut it...
