Fran offers to take care of Chester while C.C. is having some work done in her apartment. Meanwhile, C.C. gets their first feature film rights for "Lamb Chop: The Movie". Mr. Sheffield invites Shari Lewis to stay at his house, and of course Fran has to snoop around her stuff. She accidentally lets go of Chester, who eats Lamb Chop. Knowing she'll get in trouble, Fran makes a "Fran-Chop", a modified version of Lamb Chop, but Niles finds the real one in the laundry basket, and Lamb Chop decides to break the contract.
