This is not
Sparta!, THIS...IS...SPARTICUS!
This troper once had a history teacher who would insist on watching movies that had to do with historical events. As you can guess, one of these movies was Spartacus. After we finished the movie, our teacher said, "Okay, now, when you go to (insert 8th period teacher's name here)'s class, you need to stand up and say 'I'M SPARTACUS!', alright?" The class nodded. Sure enough, once 7th period passed, over half of the kids stood up and proclaimed "I'M SPARTACUS!" The teacher just stood there for a second, shook his head, said, "You guys watched that movie with (other teacher), didn't you?" Everyone nodded. Yeah, I was silent the entire time, shaking with laughter.
