Milo Murphy's Law Wiki

Murphy's Law or not, the show must go on.

— Milo Murphy

"Smooth Opera-tor" is the eighth episode in the first season of Milo Murphy's Law. It aired on October 26, 2016.[1]

Milo and friends attend the opera for extra credit, as they encounter Amanda, who attends it for her own enjoyment. When Milo ends up backstage, he decides to prevent Murphy's Law from ruining the opera for Amanda's sake.


Milo, Zack, and Melissa attend an opera to receive extra credit for Ms. White's class, running into classmate Amanda Lopez on the way. Milo himself seems very excited to see her. She admits that Milo's presence at the show makes her nervous, as she loves opera for its consistency and order; something which could be easily ruined by Murphy's Law. After assuring her that things would be fine, Milo leaves to buy some pistachios at the concession stand, only to have the vendors refuse to sell. He wears them down until they agree, but it quickly becomes obvious that they don't have any experience with the dispenser, and the resulting flood of pistachios sends Milo to the basement.

The show begins, and Zack leaves to find Milo, who'd ended up backstage in an attempt to prevent anything from going wrong. Melissa, meanwhile, does her best to keep Amanda calm despite the increasing chaos.

The clear danger on set causes one of the main actors to walk out while putting Amanda on the verge of a panic attack. Seeing this, Milo quickly takes the actor's place and the show goes on. Everyone in the audience gives a standing ovation, started by Amanda and Melissa, and the four go for pizza.
