Continuity mistake: When Eko finds the "priest" on the ground, his white clerical collar is properly on. In "Duex Ex Machina" when Locke causes the skeleton of the Nigerian "priest" to fall from the tree, the collar comes undone, and the clergy shirt is rumpled.
Continuity mistake: In the scene where Eko is walking up to the church and the woman tells him if he buys a statue the money will pay for a polio vaccine for the village, he is wearing an earring in his right ear. Once inside the church talking to his brother, his is wearing the earring in his left ear.
Continuity mistake: In this episode Jack works on an old crippled man to try and perform another "miracle." Remember, this is supposed to be in Jack's past. When he's looking at the x-rays in the beginning, take a look at the dates on them. They're November 16, 2005. In the last episode of season 2, Desmond says that the plane crashed in September 2004.
Continuity mistake: Charlie takes a step and breaks the virgin statue. Half a second later it's broken in a totally different way.
Continuity mistake: There is a shot where Sawyer tosses Jack a medicine bottle or something. First shot we see Jack reach out to catch it with his left hand. Next shot from the front Jack catches it with his right.
Continuity mistake: When the doctor takes the polaroid picture of Hurley and Dave, there are others patients behind them, right in front a window. But at a further scene, when Hurley sees the photo 'without Dave', these other patients are missing too.
Continuity mistake: At the end of the scene in the gym of the mental hospital when Hurley and Dave talk, in the background there is a guy sitting on the floor in a yoga-like position. His exact location changes between shots, as you can tell by the ground-lines. First he sits on the red line, next to where the blue and the yellow lines cross, then he sits about 5 feet further to the right, and finally he is back exactly on the same spot as in the beginning.
Continuity mistake: When Libby kisses Hurley at the cliff, there is a strand of Libby's hair which you can see hanging freely over her left cheek when the camera is on Hurley. When the camera is on Libby you see the same strand pinched between their heads. Then as the camera switches back on Hurley the strand hangs freely again. It's not possible that this happened only through the force of wind as their heads are stuck together quite tightly throughout the whole kiss.
Continuity mistake: In S.O.S., Locke is trying to remember the map he saw on the blast door. He ignores the blaring alarm until Jack reminds him, and Locke inputs the code and hits EXECUTE. The camera cuts to a shot of the numbers resetting, and then back to Locke, and he takes his finger off the EXECUTE button a second time.
Continuity mistake: In episode 2-19 SOS When Bernard is talking to Rose after she questions him in front of the group about his "sign" when the close ups are on Bernard you can see that it is raining quite heavily in the background, but when it's close up on Rose it is not raining. It doesn't begin to rain in the episode until much later.
Continuity mistake: When Locke and Mr. Eko watch the Orientation video in the pearl station Dr Chang has both arms and the screens behind him show people working in the swan hatch. His arm was badly damaged in the incident before the swan hatch was built and he should.have had a prosthetic arm when the pearl video was made.

Continuity mistake: In Episode 2-23 Live Together, Die Alone When Mr Eko runs out of the hatch when John and Desmond are faking a lock down, you see Eko put his club in his belt right in the front of his pants. In the next scene as he passes out of the door the club is gone and then when he runs back to the door as it is closing he is holding it in his hand as he drops it and it falls under the door.

Live Together, Die Alone, Part 2 - S2-E24
Continuity mistake: Penny's letter to Desmond changes as he reads it. The text stays the same, but the handwriting and position of the words on the page change between the two shots where you can see the letter from the front. Also, for the audience the letter is read aloud with Penny's voice. Interesting is the fact that there is one sentence omitted: "Sorry to be so dramatic, but these are dramatic times, are they not?" (You can read this sentence in both "versions" of the letter though).
Answer: He was eating a peice of an orange with the skin still on.
