The Crab with the Golden Claws: Part 1 - S1-E1
Continuity mistake: In order for Daws to tell Kuraki about the Karaboudjan, he tears off part of the wrapper from the Crabe Extra tin. The style of the tear changes constantly throughout this scene. The tear in the tin starts out as a tear with various ridges in the tearing. A further two shots later, the part of the tear near the end is now a lot shorter. Then a further three shots after this, the ridges in the tear have now became visibly smoother. Then when Daws chucks the can in the box, it is now just a simple tear through the wrapper. (00:01:55)
