After I watched Sunred, every time a goukon is happening, I think of it as "shindan omiai". Every. Time.
Ando is BS though.
UPDATE: Maybe it was too obscure. In an episode of Sunred, Vamp crashes a goukon in order to apologize that one of his subordinates cannot attend. With his sheer charisma, he immediately outshines other male participants and captures hearts of all girls without even trying. One of the jokes was that he's trying to leave because he "does not want to disrupt the group match-making (shindan omiai (omiai is a marriage interview; without knowing the word for goukon, he makes up a phrase for a "group marriage interview"))".
