Being a "newbie" I wouldn't know a lot of stuff about TOBOR, I have read his "christmas shopping" one his first one when he's Toby etc. then found someone else used his name and cornholing idea questions:

Who called him TOBOR?
Who made him cornhole people?

I am not 16 going on not 17, I know that I'm naive.

i think it just happened

many have tried to find the first tobor/cornhole reference and many have got bored and given up

Who knows what fear lurks in the hearts of men? MIKE BOBSICO KNOWS! And if you give him a decent tip when he delivers your mail , he might tell you.

This is the first mention of TOBOR in a comic:

Ode To Billy Joe by Wulfgar 2-20-01

Tobor's Home Funnies I will *CRUSH* you! That's O.K., I'm dying of a terminal disease anyway. The Girls Say: This is going to be good! I itch in secret places. Where will the carnage end?!? Je ne comprende pas! Sweet Home Chicago!

This is the first time TOBOR mentions CORNHOLING in a comic:

Serial Comic: the April-soft freshness of Downey by boorite 4-02-01

The Late etc. Show Mary, now that we know you're not blowing a squid, what happened after Bob Jr morphed into a huge S&M penguin? That sick bastard had me put on a killer robot disguise and play out his rape fantasies. It was the only thing that would keep him sober! RAAARRR! TOBOR WILL CORNHOLE YOU! EEEEEK! My lash hardly scratches the brute! AIIIEEEE! He intends to core sample me with his mighty hydraulics! RAAARRR... uh, Bob? This isn't really working for me. You see, I've been keeping something from you...

Boorite gave some insight into TOBOR awhile ago but I don't remember the thread.

And this is the first comic with Tobor as Tobor, not Mary Worth as Tobor:

My first sale! by boorite 4-12-01

It's TV producer Yadahentai Mobukakke! Mr. Boorite, I am here to buy the rights to your gameshow idea, "Super Robot Manrape Endurance Torture Rally." Sheez, I'm so hosed on Old Crow and Benadryl, I'll sign anything. One condition: You are first contestant. Hmmm, let me think abou-- RAAAAR! TOBOR WILL CORNHOLE YOU!

"Oh, look, a joke! How original! Thank you, but if I wanted my emotions stimulated pleasurably, I'd get a whore." - Donald B. Jones III

This series includes an explanation of Tobor's origin, though it is by no means canon.

...Trot and Cap'n Bill were free from anxiety and care. Button-Bright never worried about anything. The Scarecrow, not being able to sleep, looked out of the window and tried to count the stars.

Oh, you already read that one, sorry.

And here is a strip about monkeys!

Primal primate problem (probably) by I_am_the_Sunday_Time 10-28-01

You know the reason so many strips here suck? No monkeys. There's not a single monkey in the character set. That's just wrong. How can you explore the full range of the strip-cartoon format with no monkeys? Monkeys are the very nucleus of the comic vocabulary. We have Brad Pitt Well... maybe if he didn't shave for a week...

People shed some light on Tobor's history back in this comic competition, where I asked "Mr History" the very same question.
