Continuity mistake: While Andy continues the tour, Gabe stays behind to perform as Abraham Lincoln. Later on we see Gabe with the others, we even get a close up. A while later, when everyone is tired and sitting on the grass, Gabe doesn't seem to be there. Eventually the episode ends with Gabe finishing his performance.
Continuity mistake: Near the end of the episode when Robert California is escorting Erin out of the office, they are already in the parking lot speaking while it cuts to a shot of a concerned Andy in the conference room watching them from the window. A few moments later, Andy is shown saying goodbye to his girlfriend, while watching Robert and Erin leave the office. This should not be possible as they were shown to be in the parking lot already in a previous scene, with Andy watching as well. (00:18:38)
