Dear John - Season 2 Episode 11 Honolulu Baby

It's the second anniversary of the day John's wife left him (DJ Day), and the group is concerned because John is binging on junk food. Mrs. Philbert is preparing to attend her 60th high school anniversary, her first because she was always afraid of meeting her former fiance, Lloyd, and her best friend, Clara, who eloped together. John is deputized to escort her to New Jersey, where Lloyd and Clara show up after all -- so Mrs. Philbert introduces him as her fiance, invites them back to ""their"" place, and sets about seducing Lloyd with her patented technique: playing ""Honolulu Baby"" on the ukelele.
