Random Trivia For This Title:

  • The Allowance Evaporation: Sheldon states that deep sea divers holding their breath under water have a higher occurrence of a protein that indicates brain damage. Deep sea divers, however, don't hold their breath under water, as this is extremely dangerous and can be fatal. He possibly meant free divers.
  • The Holiday Summation: The episode won an Emmy Award for Outstanding Multi-Camera Picture Editing for a Comedy Series.
  • The Holiday Summation: When Penny and Leonard finally get the tree into the apartment, they hear a creature lurking in it. The same thing happens in National Lampoon's Christmas Vacation (1989), which also stars Johnny Galecki.
  • The Veracity Elasticity: Sheldon asks Amy to sing 2001: A Space Odyssey (1968). The proper name is 'Also sprach Zarathustra', AKA Opus 30 by [?] Richard Strauss.
  • The Fetal Kick Catalyst: Sheldon's agreeing to host a brunch shows maturation on his part. In the season six [The Big Bang Theory: The Bakersfield Expedition (2013)], Amy Farrah Fowler stated "Sheldon doesn't believe in brunch. He can't stand being at a table where one person's having an omelet and another person's having a sandwich".
  • The Fetal Kick Catalyst: Penny's name on the poster at the movie convention is cleverly hidden so not to reveal her surname.
  • The Cohabitation Experimentation: When Leonard strips down to his underwear to dance for Penny both the song and his dance moves are taken from a scene in Pulp Fiction (1994).
  • The Conjugal Conjecture: Penny's brother just got out of jail for cooking and selling meth. Dean Norris, who is also in this episode, stared in [Breaking Bad] as a DEA agent chasing a Meth dealer
  • The Cohabitation Experimentation: The Goofus and Gallant comics are intended to teach good manners and social behavior. Gallant is polite, considerate, and generous. Goofus is selfish, rude, inconsiderate, and bossy. In fact, Sheldon is almost definitively Goofus.
  • The Conjugal Conjecture: This is the second series in which Katey Sagal plays Kaley Cuoco's mother. The first one was [8 Simple Rules (2002)].
  • The Conjugal Conjecture: Keith Carradine (who plays Penny's father Wyatt) and Judd Hirsch (who plays Alfred Hofstadter) have both been nominated for Oscars - Carradine for Best Original Song "I'm Easy" from Nashville (1975) (for which he won), and Hirsch for Best Supporting Actor in Ordinary People (1980).
  • The Cognition Regeneration: Another one of her many talents, actress Melissa Rauch actually did her own ventriloquism in the scene where she has Tammy Jo St Cloud talk to her husband, Howard.
