Watch for — every moment, theme by theme

Sex & hookups 2 moments

How Sex & hookups shows up in The Big Bang Theory S8 E6:

  • Leonard Sure. In my mind, that broke the tension with comedy and led to sex.
  • Penny Well, leaving an envelope full of cash on my dresser after sex would count as weird.

Nudity & bodies 2 moments

How Nudity & bodies shows up in The Big Bang Theory S8 E6:

  • Sheldon Plus, there’s almost no chance we’ll see any of our coworkers half naked.
  • Raj Or totally naked. I love Howard, but the dude needs a little shame.

Alcohol & drugs 1 moment

How Alcohol & drugs shows up in The Big Bang Theory S8 E6:

  • Howard Talk about wasted money. What about the late fees on our credit card because somebody didn’t pay the bill on time?
