Continuity mistake: At the end of this episode, when Clarie enters the kitchen and closes the doors behind her, they are left a bit open.

Waterworks - S4-E18
Continuity mistake: Rudy blows bubbles in her milk and the bubbles rise above the glass. The shot changes to Vanessa and when it goes back to Rudy the bubbles are gone.
Continuity mistake: There are two jackets hanging (one pink on top of one blue). When we see Vanessa and her friend, Janet, fighting Theo to get through the door, the pink jacket obviously falls down. When Dr. Huxtable comes in, the jacket is seen hung up again, but when he leaves, it is on the floor again.
Continuity mistake: When Vanessa and Dabnis are talking, Vanessa sits down and takes off her coat - it falls down behind her. For the rest of the scene the coat appears and disappears on the chair behind her.
