Fillmore Easter Egg - Spenelie?

Ok, so the episode (not sure what it is called) that when the cheerleader (ilexis) changes into that nerdy person, and with the virus and everything. In the back, when they are talking to ilexis in the cafeteria, when they are moving to the conversation, you see alot of people. In the backround, you see SPANELLI from Recess, dont know why, but it made me smile, hehe.
