 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 . <unk> 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 .
