Halley Wolowitz (voice)


It's early January, 2017, and Leonard and Penny are hosting a regular dinner for their friends, the first time they've gotten together since the holidays. Each group has a story to tell which marred their holidays. Sheldon and Amy went to Texas to spend the holidays with Mary. Their issue revolves around the fact that, on Amy's initiative, they told fundamentalist Christian Mary about their cohabitation outside of wedlock. It is not only Mary's reaction to the news that has Sheldon irked, but also a secret that Amy divulges about that news. Leonard and Penny's story revolves around the day they ended up purchasing their Christmas tree, issues around which placed a pall on everything else that happened that day. And in the collective Wolowitz-Rostenkowski-Bloom household with Koothrappali thrown into the mix, they are still getting used to having baby Halley in their lives and the lack of sleep that she causes, especially in trying to get her to stop crying. It's not only the crying ... Written by Huggo

Stuart is a part of the group now?
6 January 2017 | by (India) – See all my reviews

If Raj being annoying wasn't sufficient, it seems like they have brought on Stuart too. Raj's scenes have become more and more skip-worthy every passing season and now with addition of Stuart to the group , given the amount of screen-timing he's getting, it looks like we'd be skipping half the episode.

The only good scene in the whole episode was the one at Sheldon's home in Texas.

The writers have completely run out of story and comedy. The show had always been sort of a nerdy rip off of FRIENDS but now with that scope going out of the hands too. It's important that they end this show soon.
