the grammar they don't want you to know
I'm going with fucks'
Growing up Mormon I heard "for shucks' sake" more than once.
I'm gonna go with the singular. Its too confusing to worry about all the fucks. One fuck at a time is my motto.
I don't know, but the mltshp community has an actual expert on this very subject. He wrote a book about it and everything... @grantbarrett, what say you?
Fuck sakes guys, get 'er right eh
For fuck's sakes. Never forget the ess on the end, it's for all of us fucks.
