In the first scene, we see Arnold write with his left hand.
When Helga tells Arnold, "In reality I'm just a shy girl afraid to tell you I absolutely adore you", this scene is a reference to Romeo and Juliet by Shakespeare in which Helga is Romeo and Arnold is Juliet.
Coincidentally, this scene is opposite to the one in "School Play", in which Arnold is Romeo and Helga is Juliet.
When Helga hits Brainy with the guitar offscreen, the infamous "kabong!" sound from the "El Kabong" episodes of Hanna-Barbera's Quick Draw McGraw is heard.
The song that Helga plays on the guitar is the famous Spanish instrumental "España cañí".
This episode revealed that Phoebe is aware of Helga's crush on Arnold.
