Howard is trying to file a patent for a quantum gyroscope. The university tells him he can't make any money off the patent.
Tropes:
- Blatant Lies: Raj denies wanting to get back with Emily. Penny sees right through it.
- Porn Stash: Leonard once found a stack of contracts under Sheldon's bed. He felt weird about it.
- Sex with the Ex: Raj sleeps with Emily.
- Shout-Out: Emily sends Raj a present, and it reminds him of when a character on Game of Thrones got his son's genitals sent in a box.
