Jerry is fed up with Kramer coming into his apartment any time he feels like it and asks him to return his spare set of keys. Kramer begrudgingly complies but then lets it be known that he's leaving for California. As for the others, the one key swap leads to multiple exchanges on pretty well everyone's part. When Jerry forgets his keys, he gets George to let him into Elaine's apartment so her can get his spare set. What they find interests them. Written by

The crossover with "Murphy Brown" led some people to wrongly believe this was the first time shows on competing networks cooperated on a prime-time crossover. Actually, that idea dates as far back as 1960, when Jay North of the CBS series "Dennis the Menace" (1959) took that role to ABC's "The Donna Reed Show" (1958), along with fellow "Dennis" regular Joseph Kearns, also reprising his role as Mr. Wilson.
