Have you ever heard of INTERCAL? If you haven’t, don’t feel bad. This relatively obscure language dates back to 1972 with the goal of being difficult to read and write. It is the intellectual parent of systems like brainf**k and other bad languages. Now, you can read the INTERCAL-72 source code thanks to a found printout. It will help if you can read SPITBOL, another obscure language that is a compiled version of SNOBOL (which is like an old-fashioned non-Unix awk program).
How strange it INTERCAL? Well, one of the statements is PLEASE. If you don’t use it enough, you’ll offend the interpreter, who will then ignore your program. But if you use it too much, then you are a suck up and, therefore, your program will be ignored again. If you think GOTO is a bad idea, you’ll just hate COME FROM, although that was from a later version of INTERCAL.
