The five hours later line comes from the time cards in SpongeBob SquarePants, where a deadpan narrator jumps the story forward by an exaggerated amount of time. Those cards became a standard meme shorthand for waiting far too long. This version shrinks the idea down to a blink, swapping the expected payoff for a duck quack. Short duck noises are a staple of absurdist edits and soundboards, so the combination reads instantly as a joke about delay, boredom and a result that was not worth the wait.
