The Cartoon Origin of Greg

Ladies and gentlemen, allow me to reveal a comic which helped formulate Greg. From the dim recesses of old student newspapers, let it be known that it's all Toby Morris' fault!

Toby Morris' Juniper: the Out-Of-It Alien

I should note that I had to chop the strip in half in order for it to a) remain legible, and b) fit on one page. Sorry Toby.

Nonetheless, I like the idea of aliens landing, and instead of being clearly malevolent invaders, or "new age" peace-love-and-mung-beans peddlers, they're just... guys.
