A nameless member

Continuity mistake: When the bad guys get to Jimmy's house one of them tries to open the door wearing black gloves. In the next shot you see him trying to pick the door with white doctor gloves. Why did he change? (01:03:10)

Mortug

Continuity mistake: When Mathew Perry goes to Chicago to meet with the head Boss, Bruce Willis' wife comes to talk with him at the hotel. In the scene where he is brushing his teeth he picks up the mouthwash bottle and swigs some, then sets the bottle down on the counter. The camera cuts back to her, then back to Matthew Perry, and the mouthwash is gone. (00:32:50)

Continuity mistake: When Oz realises that Jimmy "The Tulip" Tudeski is his neighbour, we see a few newspapers flying up on the screen, on the second newspaper the article with the title "His "Two Lips" are Sealed", the article text does not match the headline. (00:08:25)

Scrappy

Continuity mistake: Sometime during Matthew Perry and Bruce Willis's first meeting outside Bruce's house, Perry tells him how familiar his face is. During one of the questions, the shades Bruce hung on his shirt disappear in one shot and reappear in the next. (00:08:55)
