"I have no idea what you mean. There was a glee club at Greendale, and their bus was driving on a rainy night, and a downed power line was hanging across the road, and the bus drove through it, and it sliced through the bus and decapitated everyone, row by row, so that the people in the back had to watch all their friends get decapitated, then they got decapitated, and then the bus drove into a pool of lava. And I guess the crazy thing is, the electricity from the power line somehow kept their nervous systems ‘alive,’ so they could feel the lava. They didn’t escape the pain of the lava just because they didn’t have heads. They felt the lava. It was terrible but it was not metaphorical in any way. I would never be that petty and envious of another show’s popularity."
