Knock Knock! was the first Smashtasm extra to be filmed in Brawl. It starts with 1337Fox telling the "Interrupting Cow" and "Interrupting Sheep" Knock Knock Jokes to Super64. Finally, he tells interrupting Falcon, which ends with Super64 getting Falcon Punched.


  • SSBVET used the sound on his Melee Machinima Test.
  • This was the first machinima ever made with the North American version of Brawl.
