3. You, er... You Wanna Know... How I Got These Scars? The Dark Knight (2008)
In watching The Dark Knight, there are two entrances made by The Joker, either of which could be on this list. Since the opening bank heist is more of an undercover entrance, however, the edge goes to The Jokers unforgettable, literal entrance into the meeting of mob bosses later in the film. After making his presence known via slow, mocking laughter, The Joker pulls off a murderous magic trick with a pencil that was known to draw laughs and even applause from audiences. Technically, The Joker was acting in self-defence, so we dont have to feel so guilty about it. Besides, its perfect characterization for The Joker to make us laugh at things we shouldnt. The Jokers hilarious speech as he dresses down the biggest gangsters in Gotham is the icing on the cake for a scene that only needed one action to make its permanent mark.
