Danny's Doodles The Jelly Bean Experiment by David A. Adler*

My eight year old read this book to himself.  He liked it!  Below is his review:
"Calvin told Danny to put jelly beans in pants' pockets.   But I can't tell you what happens to them.  Calvin can read the baseball pitcher's signs so he can determine what kind of pitch he will throw.   This book is very funny!"
*Highly recommend.
