Found an absolutely delightful old computer reference book: The ResEdit All-Night Diner by Dave Ciskowski, which is entirely about tampering with pre-existing applications and system files with ResEdit and written in an unnecessary and unhinged metaphor about ordering food at a diner. Such narrow bands of human technology and culture had to intersect to make this artifact possible.

Scans are available for this and a staggering amount of other books at Vintage Apple: https://vintageapple.org/macprogramming/index_year.html
