It was called Scholastic's Comic Book Maker featuring Garfield. You (I) can buy it on Amazon!!! Is this not the most exciting piece of news you've heard all day?!?
I did some more googling and found this website that has a technically superior version of the program I used as a kid, but the options are far from the vast range I remember the program had. I remember I could add a lot more props, and many different scenes to my comic strip. I would add lasagne and outdoor scenes and funny props. But this poor=man's version is limiting my imagination.
Here's what I made tonight.

I need to investigate and play further. I need to.
