S1·E6 The Wire

Hoping to bury an unsightly telephone wire dangling over their yard, Larry and Cheryl befriend a pair of bizarre neighbors who must approve the burial. The husband is an incompetent lawyer but a big Seinfeld fan, so to appease him Larry arranges to have Julia Louis-Dreyfuss come for a visit. But when the actress arrives, the lawyer is missing; he's been hired to defend Jeff in a case involving a destructive kid Jeff sponsored for a Fresh Air Fund camp. At Larry's house, Julia ends up buying a bracelet from the lawyer's wife -- the same kind Larry wanted in episode 4 -- only to later accuse Larry of stealing it after he buys a similar one for Cheryl.
