The Big Bang Theory 'The Discovery Dissipation' Spoilers

The Big Bang Theory returns for Season 7 on Thursday night with an episode entitled "The Discovery Dissipation." Sheldon (Jim Parsons) will have an interview with NPR radio host Ira Flatow and, well, let's just say it doesn't go so well.

Fan Forum posted a taping report about the episode and revealed some spoilers about what happens during tonight's half hour. The episode opens with Sheldon doing the interview and Flatow remarks how Sheldon discovered a new element due to a mathematical error. He calls it a "wonder blunder" and compares it to stumbling on a treasure without a map. He asks Sheldon how he feels about possibly winning a Nobel Prize in Chemistry even though he works in Physics. Sheldon leaves in a huff.

Back at Leonard and Sheldon's apartment, the two men and their girlfriends Penny and Amy are having dinner. Sheldon argues with the university president on the phone and tells his friends that he feels like a trained monkey because the university is making him do interviews in order to raise funds. Leonard makes a quip that people actually like trained monkeys, while Penny is stunned because she's actually jealous of Sheldon.

Elsewhere in the episode, Raj must stay with Howard and Bernadette because his apartment is being tented. He and his dog, Cinnamon, move in for the week and Raj quickly gets on Howard's nerves as he starts acting like a more attentive version of Wolowitz as he pays compliments to Bernadette and makes her dinner.

The Big Bang Theory airs at 8 p.m. Eastern on Thursdays on CBS.
