According to the Wikipedia, if an out-of-uniform Klansman wishes to inquire if another person is a Klansman, s/he will ask, “AYAK?” (an acronym for ‘Are You A Klansman’), to which the other person will respond “AKIA” (‘A Klansman I Am’…but only if they are a Klansman. If not they’d probably just say, “…what yak?”).

I racked my poor little comedian brain trying to think of a way to incorporate this into some wordplay misunderstanding, maybe having Scapula searching for an IKEA (I don’t know why in the hell he’d be looking for an IKEA, other than to make a dumb joke work) before I gave up and went with the “Cousin Leroy” angle.
