"We wanna invite you to see Mean Girls," Gretchen Weiners (Ashley Park) interrupts, while Karen Smith (Kate Rockwell) adds that it's "a musical. People talk and sing and move their bodies all at the same time." 

"They know what a musical is, Karen. They're not idiots," Regina replies, while Gretchen still struggles with the concept.
