Michael sets his watch alarm to go off when Toby leaves. He later gives the watch to Toby as a gift. Toby then changes the watch to Costa Rican time (which would be two hours earlier), yet the alarm still goes off at the scheduled time of Toby's departure at the end of the episode.
When Michael and Hank are at Toby's desk getting ready to send him off, Toby has nothing on the wall behind him. However, when you see the wall again, it has his things hung on it still.
Once Toby opens the gift from Michael, the open part of the box shifts around.
In the cold opening, Jim answers his phone and pretends to talk to Dwight's "mater" (mother). In Fun Run (2007), after Dwight killed Angela's cat, he says they could bury the cat in the east field by his mother.
When Creed gets on the Ferris Wheel with Jim and Pam, the wheel is moving clockwise. In the next scene with Michael and Holly on the ground, as well as when they get on the ride later, the wheel is moving counter-clockwise.
Jim tells Michael about the different "firsts" he had with Pam over the years. At one point, he says, "Our first kiss, even, was ... right outside," referring to Casino Night (2006). However, Jim and Pam's first kiss was in The Dundies (2005), when Pam got drunk at Chili's and kissed Jim without really meaning to.
Not a Goof: Jim was obviously referring to a "first" kiss very much intended by at least one of them (him).
