Row, Row, Row Your Boat

"Floss, Floss, Floss Your Teeth" is a song that Arthur, Buster, the Brain, Binky, Francine, Muffy, Prunella, Sue Ellen, and another student were singing in the Dental Hygiene Choir during the intro in Arthur Cleans Up during Arthur's flashbacks. This song is a play on "Row, Row, Row Your Boat". While the students were dressed formally, Ms. Krasny (the conductor using a dental excavator instead of a stick) was wearing a dentist's coat over her dress. This song caused the kids in the crowd to start laughing.

Lyrics
[Chorus]

Floss, floss, floss your teeth

Make your mouth feel clean

Gargle and spit, gargle and spit...

[Arthur]

...to prevent gingivitis and other forms of periodontal disease.
