Fry and Bender discover that the exact pizzeria Fry worked at before coming to the 30th century is on display as part of a 20th century exhibit at the Museum of Natural History. Fry is horrified when he sees his dog, Seymour, petrified among the artifacts in the exhibit. Fry reacts with protest and learns that there is a possibility to clone his "best friend" back to life. Bender perceives Seymour as a threat to his friendship with Fry and gets his own Robo-puppy as competition.
So sad almost cried because of the way the episode ended if you like really sad stories this episode is for you.
