Chelsea's mother is shown for the first time in this episode.
While standing on their heads, Anneliese van der Pol and Amy Yasbeck are in front of a green screen.
After Victor begins to ride away and we see Raven again smiling, if you look in the background you can the see the woman who plays Irene on The Suite Life of Zack and Cody acting as a Chill Grill waitress.
Chelsea: Rae, you want to leave during The Quiet Game?
Raven: Chelsea, I wanted to leave during dinner!
Raven: Mrs. Daniels, you're like a mother to me.
Chelsea: To me too.
(Raven is trying say she's sorry while frozen)
Chelsea: I think she's saying "oil can"??
This is a reference to the 1939 movie The Wizard of Oz, where the Tin Man asked Dorothy for the oil can, while he was frozen.
