Masters puts the song "Bye Bye Love" on the record player to mask the baby's crying. He plays the first cut of the Everly Brothers' album, but "Bye Bye Love" was actually the third cut on their debut album.
The yellow telephone on Masters' desk has an RJ-type modular connector on the handset. This series is set in the late 1950s, but these connectors were not introduced by the Bell System until the mid-1970s.
