Plot

The girls take Raj out to a nightclub to find him a date. A game of Dungeons and Dragons rekindle old memories of Santa for Sheldon.

Much to Penny, Bernadette and Amy's chagrin, Leonard organizes a boys only Saturday night get together for himself, Sheldon, Howard, Raj and Stuart to play a holiday themed version of Dungeons and Dragons. The game is ultimately affected by a careless move by Raj for his love of Santa, and a calculated move by Sheldon in his disdain for the holidays. In retaliation for Leonard organizing this night, Penny organizes her own Saturday girls night out with her, Bernadette and Amy in their most provocative of clubbing outfits. Their club night out is affected by an unexpected fourth guest, who ends up being their focus for the night, and information about who in relation to the three comes to light.—Huggo

Leonard is assembling a cardboard fireplace decoration for his apartment. He is amazed that he assembled an entire fireplace with his own bare hands, even though he did get a paper-cut. Leonard tells Penny that the guys are playing Dungeons and Dragons together. Amy tells Sheldon that she always wanted to play Dungeons and Dragons. Sheldon replies that she isn't invited because men at times have to get away from civility and break out into their primal selves.

Bernadette tells Howard that she worked late so that they could be together on Saturday night. Howard tells her that if he doesn't come, then the guys will blame the failure of their night on her. Raj and Stuart had planned to have dinner and see the Christmas lights in Griffith Park, but are even more excited about joining in the game.

Their Dungeons and Dragons quest starts with a Christmas gift given to Sheldon who, as usual, is complaining about Christmas, like the overuse of "t'is" and "t'was". He pulls out a scroll from the Christmas stocking that describes their quest that starts in a village of massacred elves. They must rescue their leader Santa Claus from a pack of ogres. In-game, Howard finds a secret door, tries to set up an invasion strategy; however, Raj rushes in. He hits a tripwire that triggers a cannon, leading to his death and disqualification.

Penny pokes her head into the room and tells the guys that she thought that they should see what they are missing out on. Acting like runway model fashion models, Bernadette shows off a tight short red dress from "Forever 21" and Amy a flowered dress from "Forever 63", actually showing a lot of ankle. Penny is wearing a very short little black dress that got her out of two speeding tickets and jury duty. Raj says he wants to go, but first the girls tell him that he can't come because its girls' night but, after the girls leave, Penny pokes her head back in and invites him.

At the nightclub bar, Bernadette wants to find a girl for Raj but needs to know whether he should find a girl to get laid, casual hook-up with or a quality relationship. Amy announces that they should get him laid. The girls tell him that they could find someone and introduce him. Raj doesn't want the girl to know that he has money, but she has to be a nine or ten. Or eight if she brings another eight to the hot tub.

Back at the game, the boys' characters find a large chest. Howard wants to bury his head (i.e. boobs) in it even though he is married. The door locks behind them, and glowing words appear on the chest as the walls start to close in. The answer of the clues has Sheldon singing "Good King Wenceslas" to stop the walls from closing in. Sheldon knows the song from when his grandparents would sing carols at Christmas time.

At the nightclub, Raj finds a hot girl at the bar, they talked for a while, and he leaves her to return to the girls. He finds that she gave him a phony email address. He did when he fell for his friends' hot girlfriends, Penny and Bernadette. Amy then concludes at some point he'll fall for her. Raj says a definite "no", but Penny and Bernadette urgently try to get Raj to change his comment about Amy, but he keeps saying "no", and that he wouldn't fall for her.

Back at the apartment, Sheldon finishes the last verse of "Good King Wenceslas". Next, they find a pool of melted snowmen that Sheldon wants every detail about. Leonard wishes Sheldon would get in the spirit since he had enough crappy Christmases when he was a kid. Instead of leaving Santa milk and cookies, Leonard's family left research papers for Santa, and then in the morning they were graded. Sheldon, being Sheldon thinks they must have been great Christmases.

At the nightclub, Raj apologizes to Amy if he upset her. Amy says her first kiss was at 22, but only before she returned some guy's medicine to him. Raj claims that during a game of spin the bottle, the girl the bottle landed on said if he came close to her she would break the bottle and cut him. Amy says she fell asleep at a fraternity party in college and woke up with more clothes on. Raj says that he would sit on one hand, make it numb, and then hold hands and feel like it was another person. Amy says she does the same thing, but hers sometimes would cup her breast. Amy tells Raj that she knows what it's like to be alone and Raj agrees as they seem to connect. Amy then says "Raj wants me; now I'm good". She says that they can leave now, obviously getting back at Raj who then tells Penny on the way out that now he may fall for Amy.

During the next game stunt, Sheldon puts the answer to a puzzle on the whiteboard and the three other players use the solution that has them playing "Jingle Bells" with bells. This act lowers the drawbridge and they find the bloody and beaten Santa in the dungeon. Sheldon casts a spell of paralysis on Howard and Stuart, goes in and yells at Santa. Sheldon confesses that when, he was five, he asked Santa to bring back his Pop-Pop, Meemaw's husband, who had just died and was his only relative that urged him to follow his dream into science. Instead Santa brought him a set of Lincoln Logs. Sheldon kicks Santa and leaves him to the ogres. The others are completely shocked as they now know that Sheldon doesn't like celebrating Christmas as he was struggling to recover from such a traumatic family tragedy at the time.

That night, Sheldon comes into the living room and finds Santa Claus leaving him presents and he apologizes for not bringing back his Pop-Pop because he says that his magical power is limited. He also has something special for Sheldon, who seems excited, thinking his presents are trains. But because Sheldon left him for dead in the game, Santa fires a cannon at Sheldon for his revenge. Sheldon quickly wakes up from his nightmare.
