The Big Bang Theory Season 9 Episode 9: The Platonic Permutation
5 second plot: It’s Thanksgiving. Penny and Leonard stay at home to celebrate their first Thanksgiving as husband and wife. Sheldon and Amy go visit the aquarium as friends. And the rest of the gang volunteers at the homeless shelter.
5 second review: Aside from the horrible acting by the guest actor and Leonard wearing woman’s lingerie, this was a great episode. Good dialogue and smart ass funny.
