Seinfeld: The Strongbox (1998)

Synopsis
Kramer (Michael Richards) seeks out a secret hiding place for his new strongbox, but none of them are secret enough. Jerry (Jerry Seinfeld) hopes that a pair of cufflinks will help him break the ice with Jerry Lewis at an upcoming Friar's Club roast. Elaine (Julia Louis-Dreyfus) is obsessed -- loudly so -- by a "mystery man." And George (Jason Alexander) can't get rid of his newest girlfriend, Maura (Alex Kapp Horner), no matter how badly he behaves (and we know how bad that can be!). ~ Hal Erickson, All Movie Guide
