This is easily the best episode of the entire season. I admit that some of it was childish, but it was still hilarious. This episode features a special ed science exhibit where Nathan and Mimzy try to outdo Jimmy and Timmy. Meanwhile, Cartman's girlfriend Heidi ends up looking and acting more like Cartman. I admit that it's funny to see her get fat and be angry at everything. Every Cartman seems to think that she's gone too far! Jimmy and Timmy's project features them researching water bears or tardigrades to try to make them smarter.
Anything with Nathan and Mimzy is hilarious. They try to kill the water bears but end up making them smarter to the point where they learn how to do the hokey pokey. Some people come in to study the water bears but they're not working for the government. They're working for the NFL! They're not trying to study the water bears for concussions (which is what everyone including Jimmy and myself thought) but are trying to turn them into fans. We even see them wear little shirts and hats! That's so hilarious! ****
