Mr. Bean has a picture of a Great Western Railway steam locomotive in a frame on his wall.
One of Bean's New Year's Eve party guests hats can be seen by the clock during the decorating sketch.
After seeing this episode, US show MythBusters gave the room painting sketch a go and found it's not possible to entirely cover the room on paint.
If you look closely when Mr. Bean just starts his car, when he turns the corner you can see hands on the steering wheel in Mr. Bean's mini, meaning that Mr. Bean is not driving.
How can music play on Mr. Bean's Hi-Fi if there is no speakers?
