Posted up above, here's a collection of English pronunciation rules that English speakers have internalized so well they can't generally explain them: https://www.zompist.com/spell.html
"Ghoti" is mentioned a few times there, but basically "fish" is a nonsensical pronunciation that breaks several rules. There's a reason (well, a few reasons) why if you ask English speakers how to pronounce "ghoti" and they've never seen it before, they'll probably all guess some variation of "go-tee" or "go-tie".
That's such a dumb example because it claims to follow english rules for those letters while ignoring the actual rules. It makes a somewhat humorous joke, but people pretending that it means anything linguistically are either ignorant or intentionally trying to confuse people.
