Suite Life of Zack and Cody, The Easter Egg - Sabrina the Teenage Witch Reference

This is in the episode where Mosbley gets fired and another lady with a mole on her face replaces him. In the middle of the episode, Muriel, the cleaning lady, says, "Yeah. She's a real witch." This is a reference to Sabrina the Teenage Witch which the lady with the mole stars in as Sabrina's aunt.
