I thought this was a great episode with clever writing.
When Lisa gets sick, she must stay home from school(much to her dismay.) Marge tells her to play Bart's Dash Dingo video game to pass the time. Lisa gets addicted to the game, but must go back to school. She must cheat on a test because she forget to study, but the guilt is killing her.
Meanwhile, Homer is fattening up a Lobster named Pinchy, so he can eat the profits.
This is a great episode, with many funny Ralph quotes, like "Is this my house?", "Hi Super Nintendo Chalmers!", and "I'm learnding."
