s05e02 Jurassic Bark

Fry reads in the newspaper that archeologists have recreated an old Pizzaria from the 20th Century. He and Bender go to see it and discover that it is in fact Panucci's Pizza, the pizzeria Fry used to work at in 1999. Fry also discovers that the fossilized remains of his old dog Seymour are on display. Fry campaigns to get Seymour back and eventually does, and Farnsworth says he can use the cloning machine to bring Seymour back to life.
