Marge's Son Poisoning/Gags

Couch gag

 * The family runs in to sit on the couch, but it turns into a monster and chases them out of the house. Everyone's couches come to life and start attacking and swallowing the people sitting on them; Professor Frink is attacked by a futuristic flying couch with laser weaponry; Moe is attacked by the booths in his bar, but fights quite well with his shotgun; Homer takes refuge in a store called "Couch World", where he is piled upon by dozens of couches.
