If you're a fan of Nasty Nellie this is the episode for you. Lies, deceit, and the wheelchair push heard round the world. Plus Matt "accidentally" puts Meg's jeans in the kids drawer and a biker gang helps out a little girls lemonade stand.
This is the one that spawned a thousand memes. Nellie hurts herself falling off her horse. She's a little banged up but otherwise ok. Never the one to let the truth get in the way of opportunity though, Nellie fakes being paralyzed in order to gain the sympathy of everyone in Walnut Grove. Her plan works for a while but ultimately Laura finds out and gets her revenge in one of the all time classic Little House scenes.
