Uma thinks the sound of a toilet flushing is hilarious. In the bathroom, she flushes the toilet again and again. Grampu laughs along at first, but he soon gets annoyed and tells Uma that he's had enough of the noise. Uma decides to imitate the toilet flushing by moving her thumb up and down. She later convinces Grampu to join her, and they pretend to flush together.
A scene from this episode was used in Noggin's sign-off bumper from 2002 to 2003. The bumper was a music video about bedtime routines.
As seen in this episode, Uma used to call Grampu "Gampu" because she was young and couldn't say his name right. In the later seasons, Uma has no problem saying his name, aside from one time.
