The COW programming language is one of the funniest and most unusual coding languages ever made!
Created by Sean Heber in 2003, it’s an esoteric language (or esolang) - designed not for practicality, but for fun, creativity, and confusion.
A Humorous Twist on Brainfuck
COW is actually a variant of the Brainfuck language, one of the most famous minimalist programming languages. However, COW adds a humorous twist by replacing the symbols with “moo”-based commands - inspired by cows! 
How COW Works
The language includes 12 instructions, four more than Brainfuck. The commands look like:
Even though it sounds silly, COW is Turing-complete, meaning you could technically write any program with it - if you have the patience and a sense of humor!
Why It Exists
COW wasn’t made for real-world software - it’s a joke language, built to make programmers smile and think differently about coding. It’s part of a larger movement of esolangs, where the goal isn’t efficiency but creativity and challenge.
So next time you hear someone say "moo" in code, they might not be joking - they might be programming in COW!

,moO
,mOO
,Moo
, and others.- Only capitalization changes the command’s meaning.
- All other character combinations are ignored and treated as comments.
