I'm not sure what requires any of these characters to be of any race. Maybe referring to the ghetto was a way to be topical. The NATIONAL LAMPOON did the same thing a few years later, and though not particularly sensitive, at least they had traits attributed specifically to their ethnicity. And I don't know why these strips had three panels instead of four.
Henry Scarpelli is the father of now out-of-the-closet 80s teen idol Glenn Scarpelli. Not that it's important or anything but it's a piece of trivia you can impress friends with.
GRIN had a thing about ethnic humor when it came to the "safe" stereotypes. The character of Henry Kissinger could have been anyone German.
I think "Fred Wolf" may be a pseudonym, only because there was a "Fred Wolfe" who later wrote for CRAZY. I could be wrong though.
