The Compiler Language With No Pronounceable Acronym, abbreviated INTERCAL, is an esoteric programming language that was created as a parody by Don Woods and James M. Lyon, two Princeton University students, in 1972. It satirizes aspects of the various programming languages at the time, as well as the proliferation of proposed language constructs and notations in the 1960s. Read more on Wikipedia...
