Romeo and Juliet

"Romeo and Juliet" is a symphonic poem composed by Pyotr Tchaikovsky. It was heard in the Season One episode "Cartman Gets an Anal Probe".

Background
During the cafeteria scene, Kyle points out Wendy from the crowd, whom Stan has a crush on. While the music plays, Stan looks at her, smiles broadly, and hearts appear around his head. Cartman teases Stan, and Stan denies being in love with her. Wendy walks up to Stan to give him a letter and he barfs out of anxiety.
