The piece of trash covering the nude statue disappears after Mr Bean takes a photo of it.
When Mr. Bean is in the hospital waiting room, he sits next to a bandaged woman in a wheelchair; her grip on her hospital ticket changes.
When Mr. Bean throws his ticket into the trash bin, attempts to shove it further down and gets the bin stuck on his hand - you can plainly see that he is just holding onto the bin.
Mr. Bean gets waiting number 76 in the hospital. The first number called is 23. With the number of people waiting, there is no way Mr. Bean could have gotten number 76.
At the hospital scene, a camera crew is clearly reflected in the pot on the boy's head.
