"Slapsgiving 2: Revenge of the Slap" is the ninth episode of the fifth season of the CBS situation comedy How I Met Your Mother and 97th episode overall. It aired on November 23, 2009.
Future Ted describes the Thanksgiving of 2009, when Lily and Marshall invited the gang over to their apartment for dinner. Marshall had picked out a wonderful turkey, but had left it in the cab. Robin and Ted pick it up at the Port Authority, and in gratitude, Marshall bequeaths one of his slap bet slaps to them, on the condition they slap before sundown and decide among themselves who gets to slap Barney.
Lily's estranged father Mickey shows up. Divorced from Lily's mother, Mickey had been living in his parents' (Lily's grandparents) basement, trying to develop his strange board game ideas and taking advantage of his father's generosity. Marshall describes the look he saw in Lily's eyes at that moment, calling it the "you're dead to me" look. She had used the look on other people for trivial reasons, but she had not spoken to or of her father for three years.
Marshall, who comes from a close-knit family (he teleconferences with them for Sunday dinner), tries to convince Lily to allow her father to have dinner with them. She stubbornly refuses, but Marshall invites him in anyway, only to see Lily walk out the door. As they sit and wait for Lily to return, they play one of Mickey's unsuccessful games, "Diseases". After a part of the game sprays lead paint and horse bile all over the turkey, Marshall kicks him out and looks for Lily.
He finds her at Mr. Park's bodega, a man she had given her "you're dead to me" look. While she waited at the counter, hoping to avoid Mr. Park, she found out that he had died, which makes her depressed. Realizing what it would mean if her father died without seeing him again, they return to have Thanksgiving dinner together, inadvertently upsetting Mr. Park's widow.
Meanwhile, Ted and Robin playfully argue about who should slap Barney, begging off the honor to each other, but quickly start arguing seriously. Barney tries to extend the argument (to pass the deadline of sundown), frightened of the prospect of being tied to a chair and slapped. Eventually, Robin gifts the slap to Ted, praising his growth since being left at the altar. Ted gifts the slap to Robin, as closure to her relationship with Barney. Robin gifts the slap to Mickey as a welcome to the gang. Mickey gifts the slap to Lily as an apology for his absentee parenting. Lily can't bring herself to slap Barney, and Marshall explains that he gave out the slap to bring everyone together. A nerve-wracked Barney is released from the chair, but before he can sit down to dinner, Marshall slaps him in the face, proclaiming, "That's four!".
As a postscript, a commercial is shown of Mickey's new board game, "Slap Bet", recreating the gang's tradition of slaps as a family game.
- In the episode "Slap Bet", Barney loses a bet about Robin's past. Lily, the designated "Slap Bet Commissioner", gives Marshall the option of 10 immediate slaps or 5 to be doled out anytime "from now till eternity", pending Barney's preference. Barney chose the five, of which now four have been used: in that same episode, in "Stuff", in the episode "Slapsgiving", and in this episode, meaning there was just one more slap to go. However, in Disaster Averted, Marshal gained 3 more slaps on top of the one that was remaining. He used two of them in that episode, therefore leaving two left.
- The song Marshall created for Slapsgiving is used for the Slap Bet game commercial.
- Although Ted says he has always wanted to slap Barney, he has slapped Barney twice in episodes "The Stinsons" and "Come On".
- When there is a flashback of Lily getting ready for the wedding, Lily's wedding veil is completely unharmed. In the episode "Something Borrowed", her veil was found in the parking lot, completely ruined. This is due to Future Ted being an unreliable narrator.
- Even though Lily has issues with her father and does not speak to him, she still hired a harp player to fulfill a debt he owed in "Something Borrowed".
- In his blog, Barney complains how the Slap Bet Commissioner has not been impartial and the rules of the slap book have not been followed.
- Robin says Ted should be called Eric Slapton, in reference to musician Eric Clapton.
- In lamenting the loss of his turkey, Marshall talks about former New York Mayor Ed Koch's voice asking people to be responsible about their belongings when getting out of a taxi.
- Before Ted is supposedly about to slap Barney, Barney screams the word "Mama!" in the same tone as Freddie Mercury in "Bohemian Rhapsody".
- This episode's title is a reference to Revenge of the Sith. Star Wars itself is often mentioned throughout the series.
Donna Bowman of the AV Club rated the episode as B, saying the episode set itself up for failure by attempting to be a sequel to "Slapsgiving", one of the most popular episodes of the show.
Brian Zoromski of IGN gave the episode 8 out of 10.
