Camera Bug - S4-E10
Plot hole: At the end of the episode, when Johnny tells the guys that he sold one of his photographs for $25, Chet claims the money is his and points to everyone in the photo, noting that Captain Stanley, Marco, Mike, Roy and Johnny are all in the photo but Chet's not, which means he's the one who actually used the camera and snapped the photo. However, the itty bitty problem here is that earlier in the episode, during the rescue, we can see that after Marco heads up the hill that it's actually Chet who's with Mike, Johnny, and Roy carrying the victim up the side of the hill, alongside Captain Stanley. So the only one who could have really taken that photograph was Marco, which completely contradicts the whole bit at the end.
