Knuckle You

Okay, so the cool thing in Dylan's book right now is giving "knuckles" to people. You know, when two people make a fist and tap them together. Well, he taught Jordan to do it. That's fine. That's not what I'm concerned with. It's just that when Jordan wants to give knuckles, he announces it first. The problem? He can't pronounce "knuckles." He says "fuckles."
