I have thought hard, because I've made many weird drawings, and it was hard to pick the weirdest of them. Eventually, I recalled one so old and so weird one, so it can be counted as a champion of weirdest.
When I was a little kid, about 5-7 years old, I've drawn some primitive comics about the God in the small notebook.
I barely remember what exactly the plot was... something about how the Gods of different worlds lived in a sort of family, and the smallest God was exiled from it for some reason (I don't remember why). At the end of the comics he have created his own world and ruled it, and it was our world where we all live. So the smallest god revealed to be our God. And I remember well that this "God" was look like this:
That was how I've always imagined him as a kid. Everybody knows that this is exactly how the God looks like, right?
