Come the next morning, Amy complains to Penny that she barely got two minutes of sleep time.
- Innocent Innuendo: Amy's complaint about having little sleep time when sharing the room with Sheldon and Leonard's mention of pulling some muscle. In Amy's case, it's due to Sheldon's bad breath and his tossing and turning disrupting Amy's sleep. In Leonard's case, it's the result of himself and Penny dancing like crazy as celebration to Sheldon being out of their apartment space for the first time.

- Third Wheel: Raj comes with Howard and Bernadette to her gynecologist, feeling that he could be helpful as the son of one. Howard and Bernadette, however, just find it intrusive.
