Episode Notes

  • The title refers to Sheldon and Leonard's speculation about Mary Cooper and Alfred Hofstadter getting together the night before the Leonard & Penny's second wedding ceremony.
  • This episode was actually the third episode of The Big Bang Theory's tenth season to be taped despite being the season premiere. With the large number of guest stars in this episode, it's possible a guest's scheduling conflict led to the episode being taped out of order.
  • This will be the second time Katey Sagal has played Kaley Cuoco's on-screen mother. They both starred in the 2002-05 sitcom 8 Simple Rules.
