The Unnecessary Children's Book Sequels That Never Were Contest had a whole bunch of fun submissions that played on Shel Silverstein's The Giving Tree, so it had to make it as an honorable mention:
The Taking Tree: Shel Silverstein's sequel to The Giving Tree proves to be much less popular, as children everywhere shun trees for fear of grabby branches and thieving twigs, and parents complain about the bad morals being conveyed to their impressionable tots. Book rated highly with test audiences, but it was later revealed that test audience consisted mainly of rhododendrons. -a.fortis, Finding Wonderland
The Tree: Co-dependent No More!: A burst of insight leads the formerly Giving Tree to shed its unhealthy relationship with The Boy as it sprouts a new branch from the stump it has become. -MotherReader
Counting Rings: A Very Special Crime Scene Investigation of 'The Giving Tree': Using the current DSM-V (Diagnostic and Statistical Manual of Mental Disorders), "Counting Rings: A Very Special Crime Scene Investigation of 'The Giving Tree'" breaks down, in a child-friendly counting-book way, the psychoses and delusions behind your child's first - and favorite - dysfunctional relationship. -Lee Wind
The Irate Stump: The Giving Tree has a few regrets . . . -Jamie Michalak
The Trading Tree: The story of a cunning tree which, starting with the offer of an apple for allowance, slowly trades a young boy out of his considerable inheritance over the course of his life, leaving him with nothing but a place to sit. -Tony Dowler (not an official entry, since he's a relation...)
And one more for good measure--the unnecessary sequel to Bread and Jam For Frances:
Brie and Foie Gras For Frances: After spending a month-long summer vacation in Paris with her parents and younger sister, Frances returns home and refuses to eat anything other than brie cheese and foie gras imported from France. -Elaine Magliaro
That's it for now. Remember to check in with Saints and Spinners on Friday to see who got first place in the contest!
p.s. there are a ton of other honorable mention worthy submissions that I hope to get too in time... unfortunately, if I spend any more time on photoshop my eyes might pop out of my skull and/or my wife might stuff my laptop down the garbage disposal (with good reason).
