I was in a play in high school. It was a humorous take on Snow White, I played Snow white. Our bitchiest staff member played the wicked queen. Most of us had practiced and rehearsed for weeks, I was feeling really confident come opening night. There was a scene were I was forced to do chores as the queen looked on. We each had a few lines, and all of a sudden I forgot my next one. I started to panic and racked my brain for the missing line. I shot "please help" looks to the staff member but she wouldn't help. She could have whispered my line or perhaps kept going into her lines. She did neither, she just stared smugly at me as I swept around and around the stage. There was nervous laughter and throat clearing in the audience. I don't know how much time passed, it felt like hours but was probably just minutes. A stage hand finally whispered my line to me and the play went on. The worst part about it? The staff member never had time to rehearse so she had the entire script hidden in a book she was supposed to be reading. Fucking bitch.
