The Library - S1-E3
Revealing mistake: In the extra 'Library' scene, the book that Bean is given already has the loose pages before he has been at them with the knife. (At one point the pages get pushed forward a little bit, meaning that they're not fastened into the book.)

Revealing mistake: Just before Mr Bean rips a page out of his book, there is already a tear in it just before he actually tears it, which is not visible in any of the preceding shots.
The Library - S1-E3
Revealing mistake: When Mr Bean's book falls apart, he tries putting the book back together, and he holds one page up to the camera and it has a slight reflection as if it is glossy paper. As far as I know old books like the one Mr Bean had don't have pages like that. It's an obviously fake book.
Answer: In Mr Bean animated there is an episode where you see Mr Bean as a young boy and had the teddy then and he also liked mini cars. There is another Animated episode where Mr Bean discovers a UFO full of people who look just like him and they each have their own individual stuffed toy.
