This is the final episode with Caitlin O'Heaney as Snow Charming. When the series returned for a second season, she was inexplicably replaced with Carol Huston. No official reason has ever been given for the switch.
Snow: Besides, Elliot's gay.
Eric: Well of course he is, he's with you all the time!
Snow: No, honey....
Eric: Oh! Oh, you mean like Tweedledum and Tweedledee!
Lillian says to the Mirror, "I bet you think Bruce and Cybill really like each other!" This is a now-dated reference to the TV series Moonlighting
-- it was well-known that Bruce Willis and Cybill Shepard were less than fond of each other.
After casting a spell, Lillian exclaims, "Let those tramps from Oz top that!" Yet another reference to The Wizard of Oz
After admitting her delight over Snow's depression, Lillian hopes that "they'll write Goodyear on her side!" Reference to The Goodyear Blimp.
