- Castle: In a relationship, if you choose a movie and you choose very, very poorly, do you lose your turn?
- Esposito: How poorly?
- Beckett: Valentine’s Day.
- Esposito: You should lose two turns.
- Beckett: Where’s the host?
- Castle: Forget the host. Where’s your pants? Nah, I’ve been there. Check by the pool.
- Joey Malone: Where’s the super hot detective? (referring to Beckett)
- Esposito: You’re looking at him. Don’t laugh. I was featured in the NYPD calendar.
- "Slam It" - DJ Roc
- In this episode, the dead body breathes. It's only shortly on-screen, but visible as you can see the chest movement.
- Actor L.T. Tolliver who plays NYPD Uniform Officer referred to as LT made another uncredited appearance, his character was watching Joey Malone in breakroom before Esposito came into the room.
- This is the first time Esposito's apartment been show on Castle.
- We learn that Esposito's parents divorced when he was 5. His father remarried and moved with his wife to Florida, and after his father moved he had very little contact with him.
- Esposito had a juvenile record from 1989 that included assault, resisting arrest, and unlawful possession.
- Esposito mentions owning Assassin's Creed 3, but suggests Joey put it on "dual player mode" with Joey replying that Esposito "wouldn't get past level 1". The game's multiplayer is online-only (meaning a two-player game can't be played on a single console) nor does it use levels in the traditional sense. The error is particularly jarring for anyone who's played the game and could have been fixed by using a different game that has both features.
