Interesting thing I found out about Chilghetti....
Obviously even in 1981 the idea of putting chili over spaghetti wasn't new. Cincinnati Chili was a regional favorite for years. But this brings up something interesting.
GE aviation was centered in Cincinnati. But in the early 80's there were a lot of work being moved to the Boston branch. So there were a lot of people who were relocated from Cincinnati to Boston. Want to guess around what town a lot of them lived? Yup, Newton/Framingham. Apparently it was popular enough that there was a couple places that served the stuff back in the day.
Whoever wrote this show certainly knew about the area back in the day.
Sometimes, Just Sometimes, the joke's on you.
