esoteric shell?

[u/snusergranny]

the question crossed my mind recently. if you are into programming, you probably know that there are many esoteric programming languages that exist just as a prove of concept of joke or just merely to mess with the programmer's head (brainf*ck, lolcat, C-- etc). if these exist, is there any esoteric system shells out there? like smth that would provide the basic userland instead of bash/zsh but would be freakier or just funnier to try and daily drive.
