Godzilla's Ball Aversion

Alright listen up, nimrod. This joke is banking on wordplay. You see, it sounds like "King Kong ball" is just a ball that belongs to King Kong. But! The real knee-slapper comes from the fact that King Kong hates Godzilla! It's a play on "King Kong's ball" and the rivalry between King Kong and Godzilla. You probably still don't get it, you walnut.
