The Compiler Language With No Pronounceable Acronym (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.

There are three maintained implementations of INTERCAL dialects: C-INTERCAL (created in 1990), maintained by Eric S. Raymond and Alex Smith,, CLC-INTERCAL, maintained by Claudio Calvelli. and INTERCAL64, developed by Jason Whittington and now stewarded by PLEASE ABSTAIN.
