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.

thank you Mario for bring out some of the things I missed, great job. as Mario said, Sheldon is getting to be too much, if sassed my mother like that she would have beaten me with a rolling pin. come on writers almost 10 years of sheldons whinning and crying plus his selfish and childish ways, and that's his better qualities, is far too much.please clam him down this season and get him out of Lenard and pennys life, and everyone elses face. I know hes a big part of the show, although I don't know why, it time the other people stop pandering to him and give him some tough love. maybe then he will grow up and most of the fans of the tbbt will be extremely happy, I know I will be.

This was a pretty decent episode considering they had to cram alot into 22 minutes. This definitely should have been an hour-long premiere. The scenes with the Air Force captain should have been held until the next episode. It took away from some othe other scenes. The wedding scene was what it should have been a year ago and Penny looked absolutely glowing in her wedding dress. I also think their vows to each other seemed so sincere that they almost sounded real..Johnny to Kaley The one negative in this episode was Sheldon's obnoxious, insulting attitude to everyone, even his own mother. And couldn't he have waited until the ceremony was over to express his feelings for Leonard and Penny. I do hope they have his character grow up some this year and not inject himself into every facet of Penny & Leonard's life.

the first episode was very good, its main problem was trying to get too much story in a very short time. it was broken up too much trying to get each character some story time. but other than that pennys wedding was what it should have been the first time, the dress she wore the first time was hideous, but the dress this time was fitting for a wedding and penny looked beautiful. I agree with amina its past time for Lenard and penny to lmove out and get away from Sheldon, let someone else take care of that baby.

Maybe they did have the pet goat seated at the wedding , but from Leonard's family : his dad :( OK :) And what's Penny's family's last name ? some generic mid western German/Scandinavian writer's room burp ? Babegropen ? Methmakenson ? And the stray , scruffy cat Stuart . That darned cat.

It was good but it felt like it ended too quickly. Like I was waiting for a big twist or something big to happen but it only had small funny parts right up to the end. I'm looking forward to more episodes though and hopefully those will give us more plot twists and details about Pennys family! :) GBBT!

All things considered, this was a pretty decent episode but not a slam dunk. All the Penny/Leonard fans saw a ceremony probably worth their characters. Thought this episode was a bit rushed in terms where they had to get all the guest stars into the flow. This absolutely should have been an hour-long premiere to accomodate all. Plus, the scene with Howard and the Air Force captain could have been eliminated and used for the next episode. It just did not fit in with the wedding storyline and the time could have been utilized better with the guest stars. Hopefully. Katey Sagal, Keith Carradine & Jack McBrayer can come back in another episode.Perhaps they can have Penny and Leonard travel to Nebraska and visit her folks. Think it would be hilarious to see Leonard on a farm. One other observation was Penny's mom seemed to have met Leonard previously, but when?

I can't imagine the 9 years of Penny's family unseen characters contributing to conversations and sometimes situations, the potential for hilarity finally together, on site, 4 of them, her nuclear family, and the flat tire we got. Come on , their bucolic charm in L.A. is good for so much, the Bev Hill got many seasons out of it... They could at least have had them checked into a fancy hotel with mom and Wyatt puzzling over a bidet while brother explains it , or, a loved pet goat that made the trip and sits in a seat at the wedding

It was only ok. I thought penny's family was a big let down. No laughs there for me. Ready to get back to the core group.
Vic United States, 20:58 Sep 19 2016.
I voted Okay. The episode was chock full of laughs for sure but in places I found some of the dialogue to be too biting. Penny's family was underutilized in favor or a rather lame story line about Sheldon's mother and Leonard's father. Looking forward to the season.
