Ha! I stepped into that Hokey Cokey mess one Christmas when we were playing charades with DH's family (family tradition after Christmas dinner & lots of booze).
I wrote down Hokey Pokey on the little slip of paper to give the next person who was acting out the film/book/song/etc. Person looked confused. Much confusion ensued.
Whisper - "Oh you mean Hokey Cokey!"
"What?"
"Hokey Cokey."
"No."
"It's Hokey Cokey, isn't it?"
"No, it isn't."
"What?"
"You don't do the Hokey Pokey over here?"

And I grew up doing the Hokey Pokey a lot, because we used to roller skate for free at an old timey style roller skating rink that my uncle ran - and a skating session always included the Hokey Pokey!
