So It's Come to This: A Simpsons Clip Show

"So It's Come to This: A Simpsons Clip Show" is the 18th episode of The Simpsons' fourth season.

Synopsis
The story begins on April Fool's Day. Homer is playing pranks on Bart throughout the day. Bart, angered by the numerous tricks he has fallen for, attempts to get revenge by shaking up a beer in a paint shaker. When Homer opens the beer, it results in a massive explosion that severely injures him. Homer goes into a coma and is rushed to the hospital. As the family visits Homer, they reminisce about the events they have experienced in the past (clips from previous shows). During this time, he shows signs of life. Eventually, Bart confesses that he made the beer explode. An outraged Homer wakes up and strangles his son while the rest of his family stand next to the bed, relieved he is finally awake (Marge tells Homer at the conclusion of the story that the current date is May 16, and that Homer was in a coma for weeks).
