Yarn couch gag

Homer gets to the couch , then notices a loose thread in the cushion. He started to pull it until suddenly he got sucked in and landed a strange world inside the couch and is made of yarn. He starts walking around and spots a penny and picks it up and threw it away. He then heard a voice from a Baseball card of Mickey Mantle, which Homer lost. As the card started to speak Homer tears it. He notices a Rubix cube, but after spinning the top he started to wrestle it. Homer now heard a voice from an Alf magazine (who Homer thought was canceled too soon). Homer heard Marge's voice calling to him, and sadly thinks it's time to go. But the other beings (including the still ripped card) say his part of the couch now. Panicked he ran and tripped on the penny he threw away. As Homer ran he notices the thread being pulled up by Marge. He uses a spring to launch himself to the thread and caught it. He finally got out of the couch (though he's still yarn) and is glad to be home again. Snowball V then started play with a loose yard on Homer. Homer tells the cat to knock it, who responded by grabbing it and runs away, which makes Homer scream.
