In the small town of Assville, USA, there lived two young men with dreams bigger than their tiny little minds could handle - Zzazzu Chu and Gyudon Addict. They were best buddies since childhood, sharing everything from dirty magazines to stolen cigarettes behind the local grocery store where they worked as stock boys.

One fateful day, after hours spent discussing advanced mathematics topics such as monoids and endofunctors (which neither of them understood), these two horny geniuses discovered something truly revolutionary – a shared love for consuming yoghurts through one another's anal cavities!

It was during this momentous occasion that they realized just how much more fun it would be if they combined both passions into one glorious act of sexual expression. And thus began the legendary tale of "The Yoghurt Monoid Endofunctor"...

As time went on, word spread throughout Assville about the incredible exploits of Zzazzu and Gyudon. Their reputation grew so large that even the most prestigious universities in neighboring cities sent representatives to study their unique form of mathematical erotica.
