Most West Virginia jokes I ever heard were about a lack of indoor plumbing, falling off a mountain, and inbred relationships.
I have cousins from WV. I was from Ohio. My favorite joke was: A West Virginian and an Ohioan are standing across the Ohio River from one another. The West Virginian yells over and ask the Ohio to come over for a visit. The Ohioan say “I can’t, I got a case or diarrhea. The West Virginian yells back “well come on over, I’ll help you drink”.
Such as: if West Virginians divorce, are the still cousins?
