 At the dance , a senior citizen approaches Ron Swanson and asks for an <unk> from Duke Silver . This is a reference to the previous second season episode , " Practice Date " , which establishes Ron 's secret identity as a jazz musician . Leslie referred to her Galentine 's Day breakfast tradition as " Lilith Fair minus the <unk> and plus <unk> " , a reference to the concert tour and traveling music festival . She also said the love story between Marlene and Frank makes the 2004 romance film The <unk> look like the 2008 horror film Saw V. Mark gets Ann a necklace similar to the Heart of the Ocean , the fictional jewelry given to Kate <unk> 's character in the 1997 romantic drama film , Titanic . During one scene in " Galentine 's Day " , Leslie does a voice impersonation of U.S. President John F. Kennedy . When Tom mistakes the impression for that of the Arnold <unk> character Terminator , he prompts Leslie to do that impression as well .
