Drake kisses Josh on the cheek in the closet as a way of saying thanks for helping him cheat. This is 1 of 3 episodes in the series that involves Drake and Josh kissing.
Next door to the Premiere Theater is Schneider's Pizza, a reference to show creator and episode writer Dan Schneider.
Inside the Premiere, posters hang for features now showing - Beautiful Music, Doggy Prom, and Le Petit Fromage - which fit in with the dialogue (but not with titles on the marque).
