Jerry Seinfeld is coming out with a children's book based on one of his comedy routines. According to USA Today, Halloween (due Sept. 1) — which will feature a little Jerry character — was inspired by the comic's riff about the two C's of Halloween: candy and costumes. Although Seinfeld won't be doing the book's illustrations, he reportedly has been — and will be — very involved in the project. (Translation: He'll cash the checks.)
