The title for the episode is purposely vague. During the commentary, the cast revealed that there are actually three "secrets" in the episode: Jim's hidden feelings for Pam, Dwight and Angela's relationship, and Oscar's homosexuality. Stupkitsky later joked that there are "actually nine secrets in the episode". The cold opening – wherein Michael tries to tell a joke where the punch line is "What's up dog?" – was inspired by the same prank being pulled on Stupnitsky. The original cold opening for the episode featured Michael playing golf in his office, but it was cut.
