That Night, A Forest Grew - S2-E7
Continuity mistake: The door on his fridge keep changing. When she says "pardon my tits" it is hinged on the right, other episodes it is hinged on the left.
Suggested correction: Hinges on fridge doors can be swapped around for ease of the user.
But virtually nobody casually re-hangs their fridge doors on a whim - they set them up once and leave them. This is clearly done for the sake of visual contrivance.
Continuity mistake: Dexter kills Jimenez with a chainsaw and is wearing an apron. But he gets blood all over his shirt. He leaves in a hurry after getting a call from Rita about her door being unlocked and him having the only other key. When he shows up, there is no blood on the same shirt he was wearing.

There's Something About Harry - S2-E10
Continuity mistake: When Angel is drinking with Lila after finishing her apartment, the wine glass changes position throughout the scene.
Continuity mistake: When Doakes is carrying the packs of cocaine out of the cabin, the position of his arms and the cocaine varies wildly from shot to shot. Notable examples are that the cocaine goes from being arranged in neat, accurate stacks, to being haphazardly and irregularly stacked, and back to neat again. His grip on the cocaine also varies a lot; he starts out with straight arms, then suddenly has a 90-degree bend at the elbows, and back to straight again, all depending om camera angle. All of these changes happen too fast to have been natural, and Doakes is on camera the whole time.
