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:
[Click to view comic: 'Ode To Billy Joe']

This is the first time TOBOR mentions CORNHOLING in a comic:
[Click to view comic: 'Serial Comic: the April-soft freshness of Downey']

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:
[Click to view comic: 'My first sale!']

"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.

Oh, you already read that one, sorry.

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