Continuity mistake: After Mr. Bean has replaced the detergent with the coffee, he takes the detergent back to his seat and you can see through the plastic cup that it is only half full. But when Mr. Bean goes to take a drink out of it when the other man gets suspicious, you can now see the detergent is almost at the top. (00:10:50)
Mind The Baby, Mr. Bean - S1-E14
Continuity mistake: When Mr. Bean is playing the dart game, he cheats by putting a card on a dart and throwing it at the wall. When he throws it, the card sticks to the wall on an angle, but when he calls for the guy to look at it, the camera cuts back and now the card is straight and not on an angle. (00:17:10)
Merry Christmas Mr. Bean - S1-E10
Continuity mistake: Mr. Bean puts Christmas cards in envelopes, then seals each envelope by licking each flap. Then he puts the envelopes through the mail slot in his door, pretending that someone else mailed them to him, which is funny. Then he opens each envelope just by unfolding the flap instead of tearing open the envelope, that means that each flap had not been sealed.
Suggested correction: There is only a few moments between Bean licking the envelopes and then posting them to himself. Obviously the glue on the envelopes hasn't dried yet.
If the envelope Mr. Bean had opened were actually the envelope he had licked, then some part of the glue would have stuck, even though there were only a few seconds between licking, mailing and opening, so we would have seen him have a little resistance from the envelope when he opened the envelope. Also, he licked only one envelope, but he mailed three envelopes, so presumably prior to him coming home in the episode, he had licked the other two envelopes. Because he licked one envelope, it is reasonable he would have licked the other two envelopes earlier.

Merry Christmas Mr. Bean - S1-E10
Visible crew/equipment: When Irma asks Mr Bean if he has the turkey on, there is a shadow of the overhead mic on the wall.
Back To School Mr. Bean - S1-E15
Continuity mistake: Mr. Bean's car has a missing wheel cover on the left front wheel at the beginning of the episode, but it suddenly appears in the end before it gets destroyed by the tank. (00:04:23 - 00:22:10)
The Trouble With Mr. Bean - S1-E8
Deliberate mistake: When Bean is putting on his socks as he is driving, his foot presses the horn in the centre of the steering wheel. Except that the horn control is actually on the right-hand column stalk (you can see the horn symbol on it). This was most likely an added comical sound effect.
Merry Christmas Mr. Bean - S1-E10
Continuity mistake: Mr Bean parks his mini outside Harrods. While he is parking the car there are no people on the pavement behind the Santa Claus, but as soon as Bean gets out of the car there are several people behind Santa.
Merry Christmas Mr. Bean - S1-E10
Continuity mistake: After Mr. Bean's musical performance, there's a shot of people applauding him. There's a man at the right of the group. In the next scene that same man is seen buying the last two Christmas trees, right before Mr. Bean gets a chance to buy any. There's only five seconds between the scenes. The man couldn't have run to the Christmas tree salesman, talk to him, and pay him for the trees within those five seconds. (00:10:25)
Merry Christmas Mr. Bean - S1-E10
Revealing mistake: When Bean is driving down the street with the TV on his car, the sign for the store on the right is backwards, revealing a flipped shot.

Mind The Baby, Mr. Bean - S1-E14
Revealing mistake: In the scene where Mr Bean squeaks the baby toy and is chased by the dog, the dog handler can be seen just to the right of Mr Bean giving commands before ducking behind two extras. (00:16:15)
The Trouble With Mr. Bean - S1-E8
Continuity mistake: When Mr. Bean is putting his shirt on, there is a shot from the back of the mini and he has his brown trousers on. From the front angle, he still has his pajamas on.
Continuity mistake: Just after Mr. Bean's hand is stomped on by one of the boys, and he lets go of the diving board, the camera pans back to show him falling into the water, but the same shot shows no-one else standing on either of the diving boards. The two boys should have still been standing on the higher one.
Suggested correction: This is only an error in the "widescreen," aka cropped version of the episode. In the original 4:3 edit, you can see the two boys at the top of the screen, but the "widescreen" shot cuts them off.
And even then, the boys' legs are still visible in the widescreen version.
Merry Christmas Mr. Bean - S1-E10
Revealing mistake: The walls shake when Mr Bean slams the door on the carol singers.
