Did this happen in this series?
I watched a Modern Family episode and I am sure I saw that same sequence before, but I don't think I saw that MF episode twice, so it probably was another TV series. It went like this: Guy 1 says he had many girlfriends, guy 2 tells him to name some, guy 1 then lists some musical characters which guy 2 notices and then finishes the last name for guy 1.
I am in season 2 of B99, so it has to be season 1 or 2. Probably something Jake or Boyle said.
