Continuity: When he is playing Tetris, he is playing a different game every time.

Continuity: In the scene near the end of the movie where Peter apologizes to Joanna, Joanna is shown either in her red shirt and holding her blue jacket, or wearing her blue jacket. For instance, as Joanna is moving in to kiss Peter, she is holding the jacket, but as they embrace, she is wearing it. In the blue jacket cuts, it is much less windy, and Joanna's hair is styled differently than it is in the red shirt cuts, where her hair is blowing due to the wind.

Continuity: When Peter is shutting his computer down to try to escape his boss, one of the cuts shows that it's an OptiPlex monitor (us computer people will recognise this), then they cut back to Peter, back to the monitor and there's a piece of black electrical tape covering up the company logo on a completely different monitor.

Continuity: Toward the end of the scene where Michael, Peter and Samir are smashing the printer, the camera pulls back to show all the printer's parts around it on the grass, and its cover is off. When Michael goes back for one more blow, the printer's cover is still on it.
