In the Glee episode "Showmance", Quinn enlisted the help of five Cheerios to audition for Mr. Schuester.
In the episode, Quinn enlists the help of five Cheerios - Santana, Brittany, Britney, Lauren and Kitty - to audition for Glee Club with her. She does this in order to get out of having to participate in Cheerios practice, which she finds tedious. The five Cheerios join Quinn in a performance of "Push It" by Salt-N-Pepa, and the performance is successful enough to get them all into Glee Club.
