Onizuka, Naoshi

What a work of art!

BTW seeing as how he did so many 1-shot stories, here are a list of them in chronological order from MangaUpdates excepting the Hayate parody:

2005 Life Is Peachy?
Ch.1 - Talk About
Ch.2 - Lady Madonna
Ch.3 - Twenty Three O'Clock
Ch.4 - That's Why They Call It Love
Ch.5 - Cotton-Tail
Ch.6 - Saturday night leisure
Ch.7 - Talk Show On Mute
Ch.8 - Tsukasa and Tsubasa
Ch.9 - Sick Sad Little World
Ch.10 - The Dog And The Lady

2007 One Hot Minute
Ch.01 - You Can't Live on Love Alone
Ch.02 - Idling STEP
Ch.03 - Something in the air
Ch.04 - Siblings Of The Furthest End
Ch.05 - The Little Girl and That Clear, Cold Day
Ch.06 - Pop Song For Us
Ch.07 - HONEY
Ch.08 - The Thing Precious To You
Ch.09 - Fire cracker
Ch.10 - Special Sketch "Divine Punishment For Scissors Girl"

2008 Lovable
Ch.1 - This Is Why I Keep Saying You Can't Live On Love Alone... (1st chapter in "One Hot Minute", 3rd - "Porno Graffitti")
Ch.2 - Hug Hug
Ch.3 - Ah~ Could You Wait Just A Minute?
Ch.4 - Smile For You
Ch.5 - I Never Really Intended To Win
Ch.6 - Should We Just Go With It?
Ch.7 - Endearing with the sound turned off
Ch.8 - Magical Girl Mayuri-chan
Ch.9 - WINGS FOR YOUR HEART

2011 Porno Graffiti
Ch.1 - Isn't It Alright To Fall In Love?
Ch.2 - Fiction S
Ch.4 - Scar Tissue
Ch.5 - girl's collection
Ch.10 - People Can’t Survive on Nothing but Love... (1st chapter in "One Hot Minute", 2nd - "Lovable")

As you can see there are a couple inconsistencies. 5/7/11 all appear to have 10 chapters so I'm not sure if there might be a tenth chapter missing from Lovable. We also appear to be lacking chapter titles for PG number 3,6,7,8,9.

Also to clarify the notes in parenthesis, as best I can figure, there is a 3 part story in the 3 more recent books (7/8/11) relating to "living on love".

Chapter 1 appears in2007's OHM which I think is also chapter 1 there.
Chapter 2 appears in 2008's Lovable which I think is chapter 1 there.
Chapter 3 appears in 2009's PG which I think is chapter 10 there.

Correct me if I mixed anything up. Also if anyone could tell us the missing titles (if there are any) that would be helpful. Is there a chapter 10 in Lovable? Is there a third chapter in PG os does Fiction S encompass 2 chapters? Are there chapters 6-9 in PG or does Girl's Collection encompass 5 chapters?

Same person.

Was not aware he had other works. Clearly I must read them too.

YES
