Where the Buggalo Roam

When Amy brings her most recent boyfriend, Kif, home to meet the family, trouble ensues when Amy's parents fear that Kif cannot provide many grandchildren. Amy's parents, who own half of Mars and made a fortune off raising buggalo -- an alien version of cattle -- set out to break-up the relationship. When an entire herd of buggalo suddenly disappear, Kif offers to go after the rustlers and enlists the help of Professor, Zapp Brannigan, Fry, Leela, Hermes and Bender. Back at the homestead, Amy's parents make some interesting discoveries.
