Merry Christmas, Mr. Bean

Seeking to prepare for the big day, Mr. Bean ventures into town on Christmas Eve and visits Harrods to buy some Christmas decorations, continuing his trend of behaving inappropriately in such a prestigious department store. After parking directly at the front of the store, and harassing a man dressed as Santa Claus by plucking on his false beard[6], Bean proceeds to test two different baubles, going with one that bounces off the ground (after the other one simply smashes). He then looks to test out some Christmas lights, and managing to get into a storeroom while an employee is busy dealing with a customer, tries it out on a socket being used for the store's exterior lights, plunging the entire exterior of the store into darkness in the process.

As the employee sorts out his purchases, Bean spots the shop's Nativity scene display and performs a creative yet inaccurate story by playing around with it and some nearby toys, first by making some of the figurines shush anything that could wake the baby Jesus, having a shepherd figurine round up some toy sheep, and then having two toy tanks and a toy Dalek battle with a toy Tyrannosaurus rex, eventually having the little baby Jesus figurine airlifted by an angel attached to a magnet hanging down from a toy helicopter to the bedroom of a doll house alongside his parents' figurines. His fun is soon disrupted by the store manager - introducing a toy policeman into the Nativity scene to halt proceedings - who hands him his purchases and watches as Bean leaves the shop.

Following his fun, Bean heads to a local Christmas market, where he spots another man dressed as Father Christmas. Again he pulls the man's beard, only to find that it is real, prompting Bean to take a quick exit while the man recovers. Later, he meets up with his girlfriend, Irma Gobb, and is dragged to the shop window of a jeweller's, whereupon she tries to give him the message that she wants a sparkly ring in the display by pointing at it through the glass. Bean nods to her in agreement (albeit expressing disgust when she kisses him on the cheek), and heads into the shop, much to Irma's delight. Bean then proceeds to a butcher who is giving away a free 14 kg whole turkey in a prize to customers who can accurately guess the weight. He cheats the game by discretely standing atop a weighing scale and calculating the difference from his weight to the weight of the turkey in his hand; then successfully wins the turkey and leaves (the butcher being unaware of Bean's trick until a customer after him trips over the scale on the floor).

Afterwards, Bean volunteers to help the conductor of a Salvation Army brass band performing "God Rest You Merry, Gentlemen" at the market collect money in his bucket; in doing so, he catches a young pickpocket with a wallet in his hand and forces him to surrender all the items he stole, include cash and jewellery (notably, Bean retrieves a ring the boy hid in his mouth by smacking him on the head). Bringing these to the conductor, who secretly decides to check out what he brought back (implying that he is greedily stealing the goods rather than donating them), Bean finds himself conducting the band, and has some fun with them, before having them conduct the same song with an upbeat, jazzy feel to it, earning a big round of applause from the crowd. With the conductor now back, Bean attempts to buy a Christmas tree from a stand, only to get to the stand just as the last two trees are bought. Frustrated and wanting a tree, he cuts down the market's large tree, attaches it to the roof of his Mini and drives home with it, with everybody at the market (including the band and the conductor) completely oblivious to the theft.

Back at his flat, Bean has set up a piece of his stolen Christmas tree with his new lights and his bauble, before he leans out of his window and pushes the rest of the tree away, letting it crash onto the street below. He then writes a few Christmas cards (all of the same design) and sealing them in envelopes, then stepping outside and posting them to himself. Satisfied with his decoration, Bean searches a cupboard for some Christmas crackers, but is underwhelmed by the lack of a loud pop from one, and so decides to take out the fuses of the other crackers and stuff them all into one to make a "super cracker".

Warming up his flat with a fire, enjoying a box of chocolates and drinking a glass of sherry, Bean hangs up three stockings in his room: one for Teddy, one for himself, and one for a tiny mouse living in a hole, then he tries to find something good to watch on TV but finds only war and horror films. As he turns his TV off, he hears muffled singing coming from his door, whereupon opening it he finds a small group of young carol singers performing "Away in a Manger". Deciding to watch them perform from his seat as if he was watching TV, Bean soon becomes bored and rudely shuts the door on them just as they finish the song before heading for bed.

The following morning, Bean wakes up excited that it's Christmas morning, and proceeds to check the stockings – his is a sock that has the other sock of the pair inside; Teddy's contains a tin that holds a pair of drawing pin eyes within; the mouse's contains a piece of cheese, which Bean immediately places onto a mousetrap.

Bean soon gets to work in the kitchen on preparing the large turkey he won at the market, but while stuffing it, his watch comes off and gets lost inside. Unable to find it, Bean sticks his head into the turkey, whereupon he finds himself unable to pull it off just as his girlfriend, Irma arrives. After attempting to cover up his predicament, Irma eventually helps him to remove it, allowing Bean to recover his watch but at the cost of the turkey as it is lost out of the window in the process.

With the turkey gone, Bean and Irma instead eat cranberry sauce sandwiches along with carrot slices for dinner, whereupon Irma refuses to give Bean his present until she gets a Christmas kiss, only for him to distract her and rudely snatch it, ignoring her anger as he finds it to be a model ship. Realizing he is being forgetful, Bean produces Irma with her present, only for her excitement to turn into confusion and disappointment when he reveals that he bought her the portrait in the jeweller's display that was next to the ring, believing it to be what she really wanted. When Irma begins to sob quietly, he reveals that he "forgot the main bit", and produces a ring box, which surprises Irma. When she opens the box, however, she discovers that it contains not the ring she wanted, but a screw-in hook for hanging the portrait. A furious Irma storms out of the flat, leaving Bean puzzled and muttering to himself "What was wrong with it?" Realizing that she cannot pull his super cracker with him, he decides to do it himself, saying "Merry Christmas" to himself crestfallen. As he does so, the act cuts to a view of his window from the street, along with a sudden white flash and a loud banging sound.
