The Gang Solves the North Korea Situation - S3-E6
Continuity mistake: When Mac walks in with the duster, the red ashtray on the bar is sitting flat. When Dee is stating "That parts simply not true," the ash tray is fallen at an angle, it switches back to flat when Dennis joins the conversation, and then back to an angle when Frank tells the gang it's the North Koreans. Then it's back to flat one more time before the opening credits. (00:00:40 - 00:01:50)
