In "Costume Contest", Stanley accidentally confuses Jim's mug of orange juice for his own mug of coffee but does not appear to notice the difference. This leads a surprised Jim, along with the rest of the office, to determine what else Stanley won't notice. Kevin dresses as Phyllis; Andy sits at his desk while wearing a tie with no shirt; Jim places a cardboard box with the computer desktop on it over Stanley's monitor; Michael wears fake teeth; Michael talks about a Dunder Mifflin branch on Jupiter during a staff meeting where all the employees except Stanley is facing a different direction; Pam wears a mustache; and Dwight brings a pony into the office. Stanley did not realize any of those things happened. However, he does notice that the office clock behind him is five minutes slow, and that it's actually 5 p.m., so he immediately heads out of the office.
