My Parents Are Aliens (1999) : 4x7

Brian has a new pet: Fluffy the goldfish, but when she's fed on a diet of fried egg, bacon and beans, the unfortunate Fluffy soon floats off to the big fish tank in the sky, leaving Brian devastated. He then holds a funeral for his beloved Fluffy, which goes well. Josh attempts a challenge at the diner: eating 50 courses. He asks Brian to morph into him, and eat 48 of the courses. The first course is fish fingers, devastating Brian. He quits, leaving Josh to eat all the food. Mel later takes out insurance with dozens of spare goldfish, which she stores in the bathroom, and Brian thinks that the new fish is Fluffy back from the dead.
