This is the first episode since "Teacher's Bet" (#1.8) where Topanga (Danielle Fishel) does not appear.
In Season 2, there is a door where Harly, Joey, and Frankie hang out. Sometimes it says Boy's Bathroom. Sometimes it says GEORGE FEENY. And once, it says GEORGE WEENY. Then Feeny's office moves inside another office with "Private" on the door.
