The Aquarium is the twenty-fourth Simpsons short and was originally aired on The Tracey Ullman Show on February 28, 1988.
Homer takes the kids to the aquarium and on the way they talk about all the things they want to see. Bart says he wants to swim in the tank. They see a Moray Eel and a Sea Bass that looks like Homer’s head. Lisa then notices that Bart is swimming in the tank and Homer gets mad. Lisa is impressed when Bart does tricks while riding a shark but Homer is not. Homer screams when he sees Bart in the shark's mouth. Homer, Lisa, and Maggie then go to where they feed the sharks to wait for Bart to submerge. After a while only his lucky red swim trunks appear. Finally, Bart jumps out naked and snatches his swim trunks away from Homer and runs. Homer gets even more angry and tells Bart to come over. Bart however is being circled by a shark and says it is safer in the water than it is by Homer.
