The Big Bang Theory Season 8 Episode 22
The Graduation Transmission
Leonard is planning to go to New Jersey to give a graduation commencement speech at his old high-school. As he and Penny are about to leave, Leonard gets the news that the flight is canceled.
Meanwhile, Sheldon and Howard work on a toy drone that they can't seem to get to work.
Raj's father cuts Raj off financially because Raj spent money on the toy drone.
Penny brings Leonard a cap and gown, telling him that she called his old school and convinced them to let him give his commencement speech over Skype.
Raj gets to the apartment to find that Howard and Sheldon have disassembled the drone. After freaking out a bit, he calls his mother in hopes of pitting his parents against each other and getting his money back.
Howard and Sheldon continue working on the drone, while Leonard prepares to give his speech while wearing a graduation gown from a costume store.
Howard, Sheldon, and Raj finally give in and call tech support.
Leonard gives his speech over Skype, but realizes halfway through that his speech is boring. So, he switches gears and starts being honest about how terrible high school was. He addresses the rest of his speech to the kids who probably feel as lonely as he did in school.
While Howard and the guys wait on hold for tech support, the drone starts working on its own and starts flying out of control.
