Thanks to the participants in the C++ shame corner
This recursive text generator opens a file and prints out a random line, character by character, until a <> bracket instructs it to start or stop reading another filename.
So give it a text file “my awesome list.txt” and it chooses one line. If the line has a <token>, it will look for a file named “token” and open THAT list before returning.
With a sturdy PRNG, this is an excellent (simple) list picker for random names, restaurants, decisions, fortune telling, boilerplate text, nonsense, artistic filler and inspiration, encounters, loot etc. 
The format is so clean and intuitive, any given list like this (I just searched that up) will work just fine with no processing on your end.
Windows command line only. 
Try it yourself! I also copied the code below if you prefer to stay on-site and scoff.
