The trailblazing operating system MCP was approx 250k lines of Espol, a high-level language based on Algol with extra instructions like Halt and Heyu. Multi-processor, virtual memory, open source - this was around 40 years ago! Anyway, it had a process creation function called motherforker(); when executives realised the meaning of open source it was renamed to anabolism().
