Dad Knock Knock Joke References Frozen's Oaken Summer Blow Out Line

A knock knock dad joke that puns its way to a reference of Oaken's famous line from Frozen

The image displays a mock iMessage text exchange between a user and their dad. The dad opens with a classic knock knock joke setup: he sends "Knock knock", the user replies "Who's there?", the dad answers "You", the user responds "You who?", and the dad closes the joke with the line "Yoo-hoo big summer blow out", followed by a still of Oaken, the shopkeeper character from Disney's 2013 animated film Frozen, who says this exact line in the movie when advertising his summer sale. The gag is a corny pun that leads into a recognizable pop culture reference, leaning into the stereotype of dads telling silly, reference-heavy jokes.
