Continuity mistake: When Holmes finds Lestrade in the bar, Lestrade is seen putting his glass down, but in the next shot he's still holding the glass up. The items on the bar change around too, depending on the camera angle.

While You Were Sleeping - S1-E2
Other mistake: When Sherlock was slapped, he later says he was surprised because the girl who slapped him was a "lefty." Then he rubs his right cheek and says it's leathery from all the slaps he's gotten, while the left is soft. This is backwards - anyone hitting him with their right hand would hit his left cheek.
Sherlock Holmes: If you eliminate the impossible, whatever remains, however improbable, is the truth.
